Quasicompact endomorphisms of commutative semiprime Banach algebras
Joel F. Feinstein, Herbert Kamowitz
This paper is a continuation of our study of compact, power compact, Riesz, and quasicompact endomorphisms of commutative Banach algebras. Previously it has been shown that if …
Partial regularity and t-analytic sets for Banach function algebras
Joel Feinstein, Raymond Mortini
In this note we introduce the notion of -analytic sets. Using this concept, we construct a class of closed prime ideals in Banach function algebras and discuss some problems rel…
Lie and conditional symmetries of a class of nonlinear (1+2)-dimensional boundary value problems
Roman Cherniha, John R King
A new definition of conditional invariance for boundary value problems involving a wide range of boundary conditions (including initial value problems as a special case) is propose…
Swiss Cheeses and Their Applications
J. F. Feinstein, S. Morley, H. Yang
Swiss cheese sets have been used in the literature as useful examples in the study of rational approximation and uniform algebras. In this paper, we give a survey of Swiss cheese c…
Ellipticity Weakens Chameleon Screening
Clare Burrage, Edmund J. Copeland, James Stevenson
The chameleon mechanism enables a long range fifth force to be screened in dense environments when non-trivial self interactions of the field cause its mass to increase with the lo…
Sigma models for quantum chaotic dynamics
Alexander Altland, Sven Gnutzmann, Fritz Haake +1
We review the construction of the supersymmetric sigma model for unitary maps, using the color- flavor transformation. We then illustrate applications by three case studies in quan…
