Eight papers from a recent meeting explore areas including evolution and spectral problems related to small motions of viscoelastic fluid, functional equations and functional operator equations, isomorphism of ideals regarded as Galois modules of complete discrete valuation fields with residue field of positive characteristics, and spectral problems in singularly perturbed domains and selfadjoint extensions of differential operators. Other topics are discrete spectrum in gaps of the spectrum under strong perturbations of fixed sign, and compactification of a locally compact group. Lacks a subject index. Annotation c.
