Hecke operators as operations in elliptic cohomology

open access: yesJournal of Pure and Applied Algebra, 1990
AbstractWe construct stable operations T̄n:Ell∗( ) → Ell (ln)∗( ) for n> in the version of elliptic cohomology where the coefficient ring Ell∗ agrees with the ring of modular forms for SL2(Z) which are meromorphic at ∞, and T̄n restricts to the nth Hecke operator Tn on Ell∗.

Finite groups and Hecke operators

open access: yesMathematische Annalen, 1989
For a finite group \(G\), the author defines a Thompson series to be a formal power series \(\Gamma =\sum \gamma_nq^n\) with coefficients in the ring \(RG\) of virtual characters of \(G\) with the property that for each \(g\in G\), the series \(\Gamma_g = \sum \gamma_n(g)q^n\) is the \(q\)-expansion of a (meromorphic) modular form with signature ...
