Functional Analysis Functional analysis Functional analysis is a branch of mathematical analysis, the core of which is formed by the study of vector spaces endowed with some kind of limitrelated structure (e.g. inner product, norm, topology, etc.) and the linear functions defined on these spaces and respecting these structures in a suitable sense. The historical roots of functional analysis lie in the study of spaces of functions and the formulation of properties of transformations of functions such as the Fourier transform as transformations defining continuous, unitary etc. operators between function spaces. This point of view turned out to be particularly useful for the study of differential and integral equations. The usage of the word functional as a noun goes back to the calculus of variations, implying a function whose argument is a function. The term was first used in Hadamard's 1910 book on that subject [...More...]  "Functional Analysis" on: Wikipedia Yahoo Parouse 

Convex Function In mathematics, a realvalued function defined on an ndimensional interval is called convex (or convex downward or concave upward) if the line segment between any two points on the graph of the function lies above or on the graph, in a Euclidean space Euclidean space (or more generally a vector space) of at least two dimensions. Equivalently, a function is convex if its epigraph (the set of points on or above the graph of the function) is a convex set [...More...]  "Convex Function" on: Wikipedia Yahoo Parouse

Introduction To Algorithms Introduction to Algorithms Introduction to Algorithms is a book by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein. The first edition of the book was widely used as the textbook for algorithms courses at many universities[1] and is commonly cited as a reference for algorithms in published papers, with over 10000 citations documented on CiteSeerX.[2] The book sold half a million copies during its first 20 years.[3] Its fame has led to the common use of the abbreviation "CLRS" (Cormen, Leiserson, Rivest, Stein), or, in the first edition, "CLR" (Cormen, Leiserson, Rivest).[4] In the preface, the authors write about how the book was written to be comprehensive and useful in both teaching and professional environments. Each chapter focuses on an algorithm, and discusses its design techniques and areas of application. Instead of using a specific programming language, the algorithms are written in Pseudocode [...More...]  "Introduction To Algorithms" on: Wikipedia Yahoo Parouse

Charles E. Leiserson Charles Eric Leiserson is a computer scientist, specializing in the theory of parallel computing and distributed computing, and particularly practical applications thereof. As part of this effort, he developed the Cilk multithreaded language. He invented the fattree interconnection network, a hardwareuniversal interconnection network used in many supercomputers, including the Connection Machine Connection Machine CM5, for which he was network architect. He helped pioneer the development of VLSI theory, including the retiming method of digital optimization with James B. Saxe and systolic arrays with H. T. Kung. He conceived of the notion of cacheoblivious algorithms, which are algorithms that have no tuning parameters for cache size or cacheline length, but nevertheless use cache nearoptimally [...More...]  "Charles E.

Norm (mathematics) In linear algebra, functional analysis, and related areas of mathematics, a norm is a function that assigns a strictly positive length or size to each vector in a vector space—save for the zero vector, which is assigned a length of zero. A seminorm, on the other hand, is allowed to assign zero length to some nonzero vectors (in addition to the zero vector). A norm must also satisfy certain properties pertaining to scalability and additivity which are given in the formal definition below. A simple example is two dimensional Euclidean space Euclidean space R2 equipped with the "Euclidean norm" (see below) Elements in this vector space (e.g., (3, 7)) are usually drawn as arrows in a 2dimensional cartesian coordinate system starting at the origin (0, 0). The Euclidean norm assigns to each vector the length of its arrow. Because of this, the Euclidean norm is often known as the magnitude. A vector space on which a norm is defined is called a normed vector space [...More...]  "Norm (mathematics)" on: Wikipedia Yahoo Parouse

Computer Science Computer science Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to, information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.[1] Its fields can be divided into a variety of theoretical and practical disciplines [...More...]  "Computer Science" on: Wikipedia Yahoo Parouse 

Hahn–Banach Theorem In mathematics, the Hahn–Banach theorem is a central tool in functional analysis. It allows the extension of bounded linear functionals defined on a subspace of some vector space to the whole space, and it also shows that there are "enough" continuous linear functionals defined on every normed vector space to make the study of the dual space "interesting". Another version of the Hahn–Banach theorem is known as the Hahn–Banach separation theorem or the separating hyperplane theorem, and has numerous uses in convex geometry. The theorem is named for the mathematicians Hans Hahn and Stefan Banach, who proved it independently in the late 1920s. The special case of the theorem for the space C [ a , b ] displaystyle Cleft[a,bright] of continuous functions on an interval was proved earlier (in 1912) by Eduard Helly,[1] and a more general extension theorem, the M [...More...]  "Hahn–Banach Theorem" on: Wikipedia Yahoo Parouse 

Functional (mathematics) In mathematics, the term functional (as a noun) has at least two meanings.In modern linear algebra, it refers to a linear mapping from a vector space V displaystyle V into its field of scalars, i.e., to an element of the dual space V ∗ displaystyle V^ * . In mathematical analysis, more generally and historically, it refers to a mapping from a space X displaystyle X into the real numbers, or sometimes into the complex numbers, for the purpose of establishing a calculuslike structure on X displaystyle X . Depending on the author, such mappings may or may not be assumed to be linear, or to be defined on the whole space X displaystyle X .This article is mainly concerned with the second concept, which arose in the early 18th century as part of the calculus of variations [...More...]  "Functional (mathematics)" on: Wikipedia Yahoo Parouse
