Sergey Nikolsky Sergey Mikhailovich Nikolsky (Russian: Серге́й Миха́йлович Нико́льский; 30 April 1905 – 9 November 2012) was a Russian mathematician. He was born in Talitsa, which was at that time located in Perm Governorate, Russian Empire. He had been an Academician since November 28, 1972. He also had won many scientific awards. At the age of 92 he was still actively giving lectures in Moscow Moscow Institute of Physics and Technology. In 2005, he was only giving talks at scientific conferences, but was still working in MIPT, at the age of 100. He died on 9 November 2012, aged 107. Scientific activities[edit] Nikolsky made fundamental contributions to functional analysis, approximation of functions, quadrature formulas, enclosed functional spaces and their applications to variational solutions of partial differential equations. He created a large scientific school of functions' theory and its applications [...More...]  "Sergey Nikolsky" on: Wikipedia Yahoo

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

Partial Differential Equations In mathematics, a partial differential equation (PDE) is a differential equation that contains unknown multivariable functions and their partial derivatives. PDEs are used to formulate problems involving functions of several variables, and are either solved by hand, or used to create a relevant computer model. A special case is ordinary differential equations (ODEs), which deal with functions of a single variable and their derivatives. PDEs can be used to describe a wide variety of phenomena such as sound, heat, electrostatics, electrodynamics, fluid dynamics, elasticity, or quantum mechanics. These seemingly distinct physical phenomena can be formalised similarly in terms of PDEs. Just as ordinary differential equations often model onedimensional dynamical systems, partial differential equations often model multidimensional systems [...More...]  "Partial Differential Equations" on: Wikipedia Yahoo 

Calculus Of Variations Calculus Calculus of variations is a field of mathematical analysis that uses variations, which are small changes in functions and functionals, to find maxima and minima of functionals: mappings from a set of functions to the real numbers.[Note 1] Functionals are often expressed as definite integrals involving functions and their derivatives. Functions that maximize or minimize functionals may be found using the Euler–Lagrange equation of the calculus of variations. A simple example of such a problem is to find the curve of shortest length connecting two points. If there are no constraints, the solution is obviously a straight line between the points. However, if the curve is constrained to lie on a surface in space, then the solution is less obvious, and possibly many solutions may exist. Such solutions are known as geodesics [...More...]  "Calculus Of Variations" on: Wikipedia Yahoo 

Quadrature Formulas In numerical analysis, the Newton–Cotes formulae, also called the Newton–Cotes quadrature rules or simply Newton–Cotes rules, are a group of formulae for numerical integration (also called quadrature) based on evaluating the integrand at equally spaced points. They are named after Isaac Newton and Roger Cotes. Newton–Cotes formulae can be useful if the value of the integrand at equally spaced points is given. If it is possible to change the points at which the integrand is evaluated, then other methods such as Gaussian quadrature and Clenshaw–Curtis quadrature are probably more suitable.Contents1 Description 2 Instability for high degree 3 Closed Newton–Cotes formulae 4 Open Newton–Cotes formulae 5 Composite rules 6 See also 7 References 8 External linksDescription[edit] It is assumed that the value of a function ƒ defined on [a, b] is known at equally spaced points xi, for i = 0, …, n, where x0 = a and xn = b [...More...]  "Quadrature Formulas" on: Wikipedia Yahoo
