Infinite dimensional harmonic analysis III: proceedings of by Herbert Heyer

By Herbert Heyer

This quantity comprises contributions on fresh ends up in countless dimensional harmonic research and its purposes to likelihood conception. a few papers take care of in basic terms analytic issues corresponding to Frobenius reciprocity, diffeomorphism teams, equivariant fibrations and Harish-Chandra modules. numerous different papers comment on stochastic strategies, specifically Levy approaches. nearly all of the contributions emphasize at the algebraic-topological elements of the idea through deciding on configuration areas, in the community compact teams and hypergroups as their simple constructions. the quantity presents an invaluable survey of leading edge paintings referring to a hugely genuine part of glossy research in its natural and utilized shapings.

K-Theory: Lecture notes

Those notes are according to the process lectures I gave at Harvard within the fall of 1964. They represent a self-contained account of vector bundles and K-theory assuming basically the rudiments of point-set topology and linear algebra. one of many positive aspects of the therapy is that no need is made up of usual homology or cohomology conception.

Nonlinear functional analysis and its applications. Fixed-point theorems

This is often the fourth of a five-volume exposition of the most rules of nonlinear practical research and its functions to the ordinary sciences, economics, and numerical research. The presentation is self-contained and available to the nonspecialist. subject matters coated during this quantity comprise purposes to mechanics, elasticity, plasticity, hydrodynamics, thermodynamics, stastical physics, and specific and basic relativity together with cosmology.

I: Functional Analysis, Volume 1 (Methods of Modern Mathematical Physics) (vol 1)

This ebook is the 1st of a multivolume sequence dedicated to an exposition of practical research tools in smooth mathematical physics. It describes the elemental rules of practical research and is basically self-contained, even though there are occasional references to later volumes. we've integrated a couple of purposes once we notion that they'd offer motivation for the reader.

A Sequential Introduction to Real Analysis

Actual research presents the basic underpinnings for calculus, arguably the main precious and influential mathematical notion ever invented. it's a center topic in any arithmetic measure, and in addition one that many scholars locate difficult. A Sequential advent to genuine research provides a clean tackle actual research by way of formulating the entire underlying innovations by way of convergence of sequences.
