Division properties of commuting polynomials
Kimiko Hasegawa, Rin Sugiyama
Polynomials commute under composition are referred to as commuting polynomials. In this paper, we study division properties for commuting polynomials with rational (and integer) co…

Weighted sums of rooted spanning forests on cycles with pendant edges
Hajime Fujita, Kimiko Hasegawa, Yukie Inaba +1
We derive two formulas for the weighted sums of rooted spanning forests of particular sequence of graphs by using the matrix tree theorem. We consider cycle graphs with edges so ca…

On divergence of expectations of the Feynman-Kac type with singular potentials
Yuu Hariya, Kaname Hasegawa
Motivated by the work of Baras-Goldstein (1984), we discuss when expectations of the Feynman-Kac type with singular potentials are divergent. Underlying processes are Brownian moti…
