Enumeration of N-rooted maps using quantum field theory
K. Krishna Gopala, Patrick Labelle, Vasilisa Shramchenko
A one-to-one correspondence is proved between the N-rooted ribbon graphs, or maps, with e edges and the (e-N+1)-loop Feynman diagrams of a certain quantum field theory. This result…
Topological recursion of Eynard-Orantin and the Harmonic Oscillator
Miguel Cutimanco, Patrick Labelle, Vasilisa Shramchenko
We apply the Chekhov-Eynard-Orantin topological recursion to the curve corresponding to the quantum harmonic oscillator and demonstrate that the result is equivalent to the WKB wav…
A new relationship between block designs
Alexander Shramchenko, Vasilisa Shramchenko
We propose a procedure of constructing new block designs starting from a given one by looking at the intersections of its blocks with various sets and grouping those sets according…
