Logarithms of iteration matrices, and proof of a conjecture by Shadrin and Zvonkine
A proof for a conjecture by Shadrin and Zvonkine, relating the entries of a
matrix arising in the study of Hurwitz numbers to a certain sequence of
rational numbers, is given. The main tools used are iteration matrices of
formal power series and their (matrix) logarithms.Comment: 29 p
