Intersection numbers on M ¯ g , n $$ {\overline{M}}_{g,n} $$ and BKP hierarchy

Abstract In their recent inspiring paper, Mironov and Morozov claim a surprisingly simple expansion formula for the Kontsevich-Witten tau-function in terms of the Schur Q-functions. Here we provide a similar description for the Brézin-Gross-Witten tau-function. Moreover, we identify both tau-functio...
