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

Raimar Wulkenhaar

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 po…

Relationship between a $Φ^{4}$ matrix model and harmonic oscillator systems

Harald Grosse, Naoyuki Kanomata, Akifumi Sako +1

A Hermitian $Φ^{4}$ matrix model with a Kontsevich-type kinetic term is studied. It was recently discovered that the partition function of this matrix model satisfies the Schrödinger…

Symmetry of meromorphic differentials produced by involution identity, and relation to integer partitions

Alexander Hock, Sergey Shadrin, Raimar Wulkenhaar

We prove that meromorphic differentials $ω_{n}^{(0)} (z_{1}, ..., z_{n})$ which are recursively generated by an involution identity are symmetric in all their arguments $z_{1}, ..., z_{n}$ . The p…
