This volume contains contributions from international experts in the fields of constructive approximation. This area has reached out to encompass the computational and approximation-theoretical aspects of various interesting fields in applied mathematics.
This book collects selected peer reviewed papers on the topics of Nonlinear Analysis, Functional Analysis, (Korovkin-Type) Approximation Theory, and Partial Differential Equations. The aim of the volume is, in fact, to promote the connection among those different fields in Mathematical Analysis. The book celebrates Francesco Altomare, on the occasion of his 70th anniversary.
The current form of modern approximation theory is shaped by many new de velopments which are the subject of this series of conferences. The International Meetings on Approximation Theory attempt to keep track in particular of fun damental advances in the theory of function approximation, for example by (or thogonal) polynomials, (weighted) interpolation, multivariate quasi-interpolation, splines, radial basis functions and several others. This includes both approxima tion order and error estimates, as well as constructions of function systems for approximation of functions on Euclidean spaces and spheres. It is a piece of very good fortune that at all of the IDoMAT meetings, col leagues and...
This handbook consists of seventeen chapters written by eminent scientists from the international mathematical community, who present important research works in the field of mathematical analysis and related subjects, particularly in the Ulam stability theory of functional equations. The book provides an insight into a large domain of research with emphasis to the discussion of several theories, methods and problems in approximation theory, analytic inequalities, functional analysis, computational algebra and applications. The notion of stability of functional equations has its origins with S. M. Ulam, who posed the fundamental problem for approximate homomorphisms in 1940 and with D. H. Hy...
A collection of papers by international contributors describing new developments in the fields of univariate and multivariate approximation theory. This research has applications in areas such as computer-aided geometric design, as applied in engineering and medical technology (e.g. computerized tomography).
De-a lungul timpului am citit multe carti, unele interzise, altele greu de gasit, majoritatea cu tematica legata de ceea ce insemnau, pe scurt, misterele vazute si nevazute ale acestei lumi. La un moment dat, tot parcurgand materialele si vazand ca unele dintre acestea necesitau mai mult timp de intelegere, ne-a incoltit in minte ideea sa structuram toate notitele adunate si cu cateva explicatii suplimentare sa scriem o carte. Gandit si facut, si astfel s-a nascut cartea ,,Dincolo“, o carte minunata ce cuprinde teme pe care reprezentanti ai diverselor ramuri ale ocultismului – teozofiei, antropozofiei, doctrinei spiritiste si ezoterismului, crestin sau iudaic, oriental sau occidental, le...
Ulam Stability of Operators presents a modern, unified, and systematic approach to the field. Focusing on the stability of functional equations across single variable, difference equations, differential equations, and integral equations, the book collects, compares, unifies, complements, generalizes, and updates key results. Whenever suitable, open problems are stated in corresponding areas. The book is of interest to researchers in operator theory, difference and functional equations and inequalities, differential and integral equations. - Allows readers to establish expert knowledge without extensive study of other books - Presents complex math in simple and clear language - Compares, generalizes and complements key findings - Provides numerous open problems
