Three proofs and a generalization of the Goulden-Litsyn-Shevelev conjecture on a sequence arising in algebraic geometry
Journal of integer sequences, Tome 10 (2007) no. 3
We prove and generalize a conjecture of Goulden, Litsyn, and Shevelev that certain Laurent polynomials related to the solution of a functional equation have only odd negative powers.
Classification : 11B83
Keywords: Laurent polynomial, cohomology rings of moduli spaces, Lagrange inversion
