Neutral-Fermion constructions of factorial $g p$ -and $g q$ -Functions

Koushik Brahma, Takeshi Ikeda, Shinsuke Iwao +1

We develop neutral-fermionic constructions for the factorial $g p$ -and $g q$ -functions introduced by Nakagawa and Naruse, which are respectively dual to the factorial $GQ$ - and $GP$ -…

An elementary construction of the ring of dual $K$ - $Q$ -cancellation property

Shinsuke Iwao

This paper presents an elementary introduction on $K$ -theoretic $Q$ -functions, which were introduced by Ikeda and Naruse in 2013. These functions, which serve as $K$ -theoretic anal…
