Complexified Virasoro Flow and the Logarithmic Graviton at the Chiral Point
Yannick Mvondo-She
At the chiral point of topologically massive gravity, the massive graviton becomes degenerate with the left-moving graviton, leading to the appearance of a logarithmic mode and a c…
Analytic Properties of the Jost Functions via the Poincaré-Picard Theorem
Yannick Mvondo-She
The analytic properties of the Jost functions are fundamental in quantum scattering theory and in the analytic continuation of the scattering matrix into the complex energy plane.…
From monodromy to : reconstructing the logarithmic sector of chiral TMG from virasoro flow
Yannick Mvondo-She
We construct and analyze the logarithmic sector of chiral Topologically Massive Gravity (TMG) at the critical point from the perspective of Virasoro evolution and radia…
Virasoro Zero-Mode Flow in Critical Topologically Massive Gravity: Logarithmic Correlators and Partition Function Grading
Yannick Mvondo-She
We study the rank-two logarithmic sector of critical Topologically Massive Gravity through the Virasoro zero-mode action \[ U(s,\bar s)=e^{-sL_0-\bar s\bar L_0}. \] Writing $L_0=h\…
Monodromy, Logarithmic Sectors, and Two-Point Functions in Critical Topologically Massive Gravity
Yannick Mvondo-She
We investigate the structure of logarithmic modes in critical topologically massive gravity (CTMG) at the chiral point from the perspective of analytic continuation and m…
On palindromic numerators of bigraded symmetric orbifold Hilbert series and Kostka-Foulkes polynomials
Yannick Mvondo-She
From our work on partition functions in log gravity, we show that the palindromic numerators in two variables of bigraded symmetric orbifold Hilbert series take the form of sums of…
