Half-Spin Tautological Relations and Faber's Proportionalities of Kappa Classes
We employ the -spin tautological relations to provide a particular
combinatorial identity. We show that this identity is a statement equivalent to
Faber's formula for proportionalities of kappa-classes on ,
. We then prove several cases of the combinatorial identity, providing
a new proof of Faber's formula for those cases
A combinatorial identity
We give an elementary proof of an interesting combinatorial identity which is of particular interest in graph theory and its applications
A combinatorial identity for studying Sato-Tate type problems
We derive a combinatorial identity which is useful in studying the
distribution of Fourier coefficients of L-functions by allowing us to pass from
knowledge of moments of the coefficients to the distribution of the
coefficients.Comment: This paper contains the proof of a combinatorial identity used to
study effective equidistribution laws for the Fourier coefficients of
elliptic curve L-functions investigated by the first two authors in
