A quadratic critical-value conjecture for the fifth Bessel moment
Jonas Matuzas
We conjecture an explicit evaluation of the pure fifth Bessel moment as a quadratic expression in the critical value of the weight-three, leve…
Closed-form evaluation of the cyclic four-electron atomic correlation integral
Jonas Matuzas
For positive exponents we evaluate the cyclic four-electron Slater integral, the topology recorded as case V in Bonham's 1965 classification, in a finite real expr…
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 strict gap above the Brito--Chacon--Naveira bound for the Sasaki volume on higher odd spheres
Jonas Matuzas
For a smooth unit vector field on the round sphere , its Sasaki volume is the volume of its graph in the unit tangent bundle. Brito, Chacón and Naveira proved that th…
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…
A Non-Reciprocal Elliptic Spectral Solution of the Right-Angle Penetrable Wedge Transmission Problem for
Jonas Matuzas
We consider the two-dimensional time-harmonic transmission problem for an impedance-matched (ρ= 1) right-angle penetrable wedge at refractive index ratio ν= \sqrt{2}, in the integr…
