Archimedean Zeta Integrals for Unitary Groups
We prove that certain archimedean integrals arising in global zeta integrals involving holomorphic discrete series on unitary groups are predictable powers of π times rational or algebraic numbers. In some cases we can compute the integral exactly in terms of values of gamma functions, and it is plausible that the value in the most general case is given by the corresponding expression. Non-vani...

متن کاملIntroduction: homological and commutative algebra
Naive set theory is the typical background or foundation for constructing more complicated structures, in a century-old tradition. The modifier naive denotes an informal and non-axiomatic treatment, in contrast to versions of set theory specifically aimed at preventing paradoxes by limiting constructions. Part of the set theory tradition demands that any mathematical discussion be compatible wi...
متن کامل08b. Examples of spectra of operators
Proof: That λ 6∈ σ(T ) is that there is a continuous linear operator (T−λ)−1. We claim that for μ sufficiently close to λ, (T − μ)−1 exists. Indeed, a heuristic suggests an expression for (T − μ)−1 in terms of (T − λ)−1. The algebra is helpfully simplified by replacing T by T + λ, so that λ = 0. With μ near 0 and granting existence of T−1, the heuristic is (T − μ)−1 = (1− μT−1)−1 · T−1 = ( 1 + ...
