A recursive method for the oddness of the number of set-valued tableaux
Taikei Fujii, Takahiko Nobukawa, Tatsushi Shimazaki
Set-valued tableaux, introduced by Buch to express the tableaux-sum formula for stable Grothendieck polynomials, generalize semistandard tableaux. We provide a new recursive proof…
Hypergeometric solutions for variants of the -hypergeometric equation
Taikei Fujii, Takahiko Nobukawa
We introduce a configuration of a -difference equation and characterize the variants of the -hypergeometric equation, which were defined by Hatano-Matsunawa-Sato-Takemura, by…
Connection formula for the Jackson integral of Riemann-Papperitz type
Taikei Fujii, Takahiko Nobukawa
We give a connection formula for the Jackson integral of Riemann-Papperitz type. This includes a solution of the connection problem for the variant of -hypergeometric equation o…
Special values of Grothendieck polynomials in terms of hypergeometric functions
Taikei Fujii, Takahiko Nobukawa, Tatsushi Shimazaki
We give some special values of Grothendieck polynomials and an explicit formula for the number of set-valued tableaux. For Young diagrams consisting of a single row or a single col…
