• ### ALGEBRAIC GEOMETRY

Note immediately one diﬀerence between linear equations and polynomial equations: theorems for linear equations don’t depend on which ﬁeld k you are working over, 1 but those for polynomial equations depend on whether or not k is algebraically closed and (to a lesser extent) whether k has characteristic zero. Since I intend to emphasize the geometry in this course, we will work over algebraically closed ﬁelds for the major part of the course.

• ### Đề tài " On the homology of algebras of Whitney functions over subanalytic sets "

In this article we study several homology theories of the algebra E ∞ (X) of Whitney functions over a subanalytic set X ⊂ Rn with a view towards noncommutative geometry. Using a localization method going back to Teleman we prove a Hochschild-Kostant-Rosenberg type theorem for E ∞ (X), when X is a regular subset of Rn having regularly situated diagonals. This includes the case of subanalytic X. We also compute the Hochschild cohomology of E ∞ (X) for a regular set with regularly situated diagonals and derive the cyclic and periodic cyclic theories. ...

• ### The Relational Algebra and Calculus

The basic set of operations for the relational model is known as the relational algebra. These operations enable a user to specify basic retrieval requests. The result of a retrieval is a new relation, which may have been formed from one or more relations. The algebra operations thus produce new relations, which can be further manipulated using operations of the same algebra.

• ### Improve efficiency of fuzzy association rule using hedge algebra approach

This paper proposes a method for mining fuzzy association rules using compressed database. We also use the approach of Hedge Algebra (HA) to build the membership function for attributes instead of using the normal way of fuzzy set theory. This approach allows us to explore fuzzy association rules through a relatively simple algorithm which is faster in terms of time, but it still brings association rules which are as good as the classical algorithms for mining association rules.

• ### A probabilistic relational database model and algebra

This paper introduces a probabilistic relational database model, called PRDB, for representing and querying uncertain information of objects in practice. To develop the PRDB model, first, we represent the relational attribute value as a pair of probabilistic distributions on a set for modeling the possibility that the attribute can take one of the values of the set with a probability belonging to the interval which is inferred from the pair of probabilistic distributions

• ### Solution of Linear Algebraic Equations part 8

A system of linear equations is called sparse if only a relatively small number of its matrix elements aij are nonzero. It is wasteful to use general methods of linear algebra on such problems, because most of the O(N 3 ) arithmetic operations devoted to solving the set of equations or inverting the matrix involve zero operands. Furthermore, you might wish to work problems so large as to tax your available memory space, and it is wasteful to reserve storage for unfruitful zero elements.

• ### Solution of Linear Algebraic Equations part 1

• ### Exercise Book for An Introduction to Relational Database Theory

This is the exercise book to accompany the present author's An Introduction to Relational Database Theory. With two exceptions, these exercises are copies of those given at the ends of Chapters 1-7 of that book. The exercises using Rel given with some of those chapters are also included. The first exception is Exercise 7 for Chapter 7, which I have replaced by a precise, detailed specification for a comprehensive database design. The second is a set of additional exercises using Rel, exploring virtual relvars and user-defined type definitions....

• ### Đề tài " Determination of the algebraic relations among special Γ-values in positive characteristic "

We devise a new criterion for linear independence over function ﬁelds. Using this tool in the setting of dual t-motives, we ﬁnd that all algebraic relations among special values of the geometric Γ-function over Fq [T ] are explained by the standard functional equations. Contents 1. Introduction 2. Notation and terminology 3. A linear independence criterion 4. Tools from (non)commutative algebra

Following a brief introduction and overview, early chapters cover the basic algebraic relationships of entropy, relative entropy and mutual information, AEP, entropy rates of stochastics processes and data compression, duality of data compression and the growth rate of wealth. Later chapters explore Kolmogorov complexity, channel capacity, differential entropy, the capacity of the fundamental Gaussian channel, the relationship between information theory and statistics, rate distortion and network information theories.
