Shifted poles and chamber cancellation for classical Witten zeta functions

Jonas Matuzas

We determine two infinite families of poles on the positive real axis for classical single-variable Witten zeta functions. In type , for , the point $q_r^A = 2(r-4)/…

Second-pole wall periods for Witten zeta functions in the classical families

Jonas Matuzas

Let Phi be an irreducible reduced crystallographic root system of rank r, and let N be the number of positive coroots. A previous theorem (arXiv:2608.16363, Theorem 3.3) identifies…

The second pole of Witten zeta functions and exact evaluations in types F4 and D5

Jonas Matuzas

Let Phi be an irreducible reduced crystallographic root system of rank r at least 2, let N = |Phi^+| be the number of positive roots, and let h be its Coxeter number. For the norma…

A universal leading-residue formula for Witten zeta functions

Jonas Matuzas

Let be an irreducible crystallographic root system of rank , with Coxeter number , Weyl group , Cartan matrix , and invariant degrees .…

Generic polar divisors and flag residues for root-system zeta functions

Jonas Matuzas

Let be an irreducible crystallographic root system, and let denote the untwisted Komori-Matsumoto-Tsumura zeta function with one exponent for each positive co…

A Non-Reciprocal Elliptic Spectral Solution of the Right-Angle Penetrable Wedge Transmission Problem

Jonas Matuzas

We study the two-dimensional time-harmonic scalar transmission problem for an impedance-matched penetrable right-angle wedge: the exterior medium has wavenumber k_0 and the interio…
