A quadratic identity in the shuffle algebra and an alternative proof for de Bruijn's formula

18 Jun 2020 Colmenarejo Laura Diehl Joscha Sorea Miruna-Stefana

In this paper, we prove an intriguing identity in the shuffle algebra, first observed in [CGM19] in the setting of lattice paths. It has a close connection to de Bruijn's formula when interpreted in the framework of signatures of paths...
