Linear relations supplementing BKP for the Kontsevich matrix model with even potential

Wulkenhaar, Raimar

Zusammenfassung

With G. Borot we have previously proved that moments of the Kontsevich matrix model with arbitrary potential satisfy quadratic BKP relations. In this note we show that, for even potential, these moments also satisfy simpler linear relations, which are organised by elementary Schur Q-functions.
