Equality of two quadrant marked mesh pattern polynomials
Let denote the polynomial associated with 132-avoiding permutations and the indicated quadrant marked mesh pattern parameters. The parameters are and , with .
Equality conjecture. For all , we have
The equality is motivated by the observed coincidence of the corresponding polynomials. Its resolution is not specified in the supplied text.
