Модель: In this monograph we use new methods to originate the definition for the tensor product of two topological semigroups so that it inherits the topological properties and we showed the existence and uniqueness of topological tensor product for two topological semigroups with identities and in general for a finite collection of topological semigroups which is somehow complicated. Then the ideal structure, minimal ideals, maximal subgroups and idempotents of the topological tensor product were explained. The concept of compactification and function spaces of a topological tensor product were investigated and in general, the relation between p-compactification of topological semigroups S and T and their tensor product are discussed, where p is an arbitrary property of compactification. Finally, by using topological tensor product technique the function spaces of Ress matrix semigroup were characterized. - посмотрите hamidreza rahimi tensor product on semigroups на сайте интернет-магазина.
Модель: In 1955, Grothendieck systematically introduced the general theory of tensor products for Banach spaces. As for Banach lattices case, in 1974 and 1972, Wittstock and Fremlin respectively introduced the Wittstock (positive) injective and Fremlin (positive) projective tensor product for Banach lattices. In 2006, Bu and Buskes used l_p as a special case, discussed the Radon-Nikodym property for the Wittstock and Fremlin Tensor products of l_p and Banach lattices. Based on that result, we improved the result to Orlicz sequence space, a more generalized case. In this dissertation, we first introduce several Banach lattice-valued sequence spaces. By proving they are isometrically isomorphic and Riesz isomorphic to the Wittstock injective tensor product and Fremlin projective tensor product respectively, we then use them as the sequential representations of these two positive tensor products. Finally, by studying these sequential representations, we obtain characterizations of the Radon-Nikodym property on these two positive tensor products. - посмотрите hamidreza rahimi tensor product on semigroups на сайте интернет-магазина.
Модель: Being able to reverse engineer from point cloud data to obtain three-dimensional (3D) models is important in modeling. This thesis presents a new method to obtain a tensor product B-spline representation from point cloud data by fitting surfaces to appropriately segmented data. Point cloud data obtained by digitizing 3D data, typically presents many associated complications like noise and missing data. Our method addresses all these issues. This work presents a framework that works robustly in the presence of holes in the data and is straightforward to implement. The original contribution of this work includes a new method to fill triangulated surfaces with missing data, a new curve smoothing algorithm based on the MLS Projection and a new method to fit B-spline surfaces by blending local fits. This work is the outcome of research carried out under the guidance of Prof. Elaine Cohen at the University of Utah. - посмотрите hamidreza rahimi tensor product on semigroups на сайте интернет-магазина.
Модель: In this thesis we address certain questions arising in the functional analytic study of dynamical systems and differential equations. First, we discuss the operator theoretic counterparts of the central ergodic theoretical notions of strong and weak mixing. These concepts correspond to particular types of asymptotic behaviour of operator semigroups in the weak operator topology. In particular, we carry over classical theorems of Halmos and Rohlin for measure preserving transformations to the Hilbert space operator setting. Further, we illustrate operator semigroup methods and results on a class of telegraph systems with various boundary conditions. We study both linear and nonlinear boundary value problems. The stability of linear telegraph systems is discussed by applying theorems from the previous chapters. For the existence of solutions, we are particularly interested in time-dependent boundary conditions, since this case has little been investigated so far. - посмотрите hamidreza rahimi tensor product on semigroups на сайте интернет-магазина.
Модель: In this book we will consider two topics of the algebraic structures which concern the properties of finitely presented groups and semigroups. The first problem which we examine is the calculating of the Fibonacci length of two families of finitely presented groups. Also we get two applications of the Fibonaccilength on the classification of groups and graphs. These applications are theoretical results of this notion after all of its nice numerical results. The second problem which is investigated is a classification method for groups (the permutational property) which considered in 1987 by P. Longobradi and M.Maj. We mainly concentrate on the generalization of this property to the semigroups by using some combinatorial methods. Finally, we give GAP cod and present two programs that first calculate the Wall number of a given prime p and second Computes the order of finite semigroups. - посмотрите hamidreza rahimi tensor product on semigroups на сайте интернет-магазина.
Модель: This book is a nice expository text to the study of elementary operators and tensor products.Technically speaking, tensor product is a technical approach used in analysis in solving problems and it is one of the nice approaches used in solving problems involving properties of elementary operators. good and simple examples are used for easy understanding of the book. There are also several examples that can help the learner to relate the ideas in this book with applications in other areas like physics. - посмотрите hamidreza rahimi tensor product on semigroups на сайте интернет-магазина.
Модель: The purpose of this thesis is to investigate some aspects of fuzzification of semigroups, partially ordered semigroups and gamma semigroups. In this thesis the concepts of fuzzy subsemigroups, fuzzy bi-ideals, fuzzy (1,2)-ideals, fuzzy quasi ideals, fuzzy ideals, fuzzy interior ideals, fuzzy prime and fuzzy semiprime ideals, cartesian product of fuzzy ideals, fuzzy prime ideals and fuzzy semiprime ideals, fuzzy ideal extensions in a gamma semigrouop have been introduced. These concepts are also studied via operator semigroups of a gamma semigroup. In this thesis some results of gamma semigroups have been rediscovered in terms of fuzzy subsets. Here some important characterization theorems in terms of fuzzy subsets have been obtained. It is important to note here that in the study of gamma semigroups in terms of fuzzy subsets operator semigroups play a crucial role. - посмотрите hamidreza rahimi tensor product on semigroups на сайте интернет-магазина.
Модель: Actions of a semigroup on a set have always been a useful tool to study mathematical structures, and recently have captured the interest of some computer scientists, too. For this reason and because of its close relation to the category of sets, one can take the category of S-acts, for a semigroup S, as the universe of discourse to study mathematical notions in it. The sequentially dense monomorphisms of acts, which are also of interest to computer scientists, was first defined by Giuli, Ebrahimi and Mahmoudi, for projection algebras. Then this notion of sequentially dense monomorphisms was generalized to acts over an arbitrary semigroup and injectivity, which also may be said to be the most central notion in many branches of mathematics, with respect to them have been studied by Ebrahimi, Mahmoudi, and Moghaddasi. These encouraged the author to present some extensions of behaviour of this notion of injectivity. - посмотрите hamidreza rahimi tensor product on semigroups на сайте интернет-магазина.

Модель: The work is organized as follows: We give basic definitions from group theory and group representations, with some examples. We represent all the irreducible representations of the symmetry group S(n), we define the notion of the Young diagram and show that the number of inequivalent irreducible representation of S(n) is the same as the number of different Young diagrams. We also define the Hook formula for dimensions. We give a background of algebraic material and define the Young symmetrizer operator. We give a brief introduction to tensor algebra. In order to clarify the relation between the group GL(V) (in this paper we concentrate on the group S(n)GL(V)) and the tensor space we give an alternative definition of the tensor space T^(n)(V) as C[S(n)]-Module. The standard tableau are defined and the corresponding decomposition of the tensor space is given. We decompose the spaces T^(2)(V); T^(3)(V) and T^(4)(V). We decompose the tensor spaces for n = 2; 3; 4 according to the subgroup O(n) of GL(V). In this work we are dealing with a "bare" vector space. Our main aim is to study the irreducible tensor decompositions of vector spaces with additional structures. - посмотрите hamidreza rahimi tensor product on semigroups на сайте интернет-магазина.
