ANALYTIC CONTINUATION IN REPRESENTATION THEORY AND HARMONIC ANALYSIS by
— In this paper we discuss topics in harmonic analysis and representation theory related to two different real forms G/H and Gc/H of a complex semisimple symmetric space GC/HC. We connect representations of G and G c using the theory of involutive representations of semi-groups and reflection symmetry. We discuss how to generalize the Segal-Bargmann transform to real forms of bounded symmetric ...
متن کاملAnalytic Continuation of the Harmonic Sums for the 3–Loop Anomalous Dimensions
We present for numerical use the analytic continuations to complex arguments of those basic Mellin transforms, which build the harmonic sums contributing to the 3–loop anomalous dimensions. Eight new basic functions contribute in addition to the analytic continuations for the 2–loop massless Wilson coefficients calculated previously. The representations derived have a relative accuracy of bette...

متن کاملAnalytic and Algorithmic Aspects of Generalized Harmonic Sums and Polylogarithms
In recent three–loop calculations of massive Feynman integrals within Quantum Chromodynamics (QCD) and, e.g., in recent combinatorial problems the so-called generalized harmonic sums (in short S-sums) arise. They are characterized by rational (or real) numerator weights also different from ±1. In this article we explore the algorithmic and analytic properties of these sums systematically. We wo...
متن کاملOn Effective Analytic Continuation
Until now, the area of symbolic computation has mainly focused on the manipulation of algebraic expressions. It would be interesting to apply a similar spirit of “exact computations” to the field of mathematical analysis. One important step for such a project is the ability to compute with computable complex numbers and computable analytic functions. Such computations include effective analytic...
