Li filtrations of SUSY vertex algebras

Shintarou Yanagida

Any vertex algebra has a canonical decreasing filtration, called Li filtration, whose associated graded space has a natural structure of a vertex Poisson algebra. In this note, we…

Specializing Koornwinder polynomials to Macdonald polynomials of type and

Kohei Yamaguchi, Shintarou Yanagida

We study the specializations of parameters in Koornwinder polynomials to obtain Macdonald polynomials associated to the subsystems of the affine root system of type $(C_n^\vee,C_n)…

Gelfand pairs and spherical functions for Iwahori-Hecke algebras

Shintarou Yanagida

We introduce the notion of Gelfand pairs and zonal spherical functions for Iwahori-Hecke algebras.

Stochastic behavior of outcome of Schur-Weyl duality measurement

Masahito Hayashi, Akihito Hora, Shintarou Yanagida

We focus on the measurement defined by the decomposition based on Schur-Weyl duality on qubits. As the first setting, we discuss the asymptotic behavior of the measurement outc…
