Commentarii Mathematici Helvetici, 81(2), 481–494. https://doi.org/10.4171/cmh/60Higher order automorphic forms have recently been introduced to study important questions in number theory and mathematical physics. We investigate the connection between these functions and Chen's iterated integrals. Then using Chen's theory, we pro... Read More about Iterated integrals and higher order automorphic forms.

Journal of the London Mathematical Society, 80(1), https://doi.org/10.1112/jlms/jdp015In this paper a theory of Hecke operators for higher-order modular forms is established. The definition of higher-order forms is extended beyond the realm of parabolic invariants. A canonical inner product is introduced. The role of representation th...

Diamantis, N., & O'Sullivan, C. Kernels for products of L-functions. Algebra and Number Theory, 7(8), https://doi.org/10.2140/ant.2013.7.1883The Rankin-Cohen bracket of two Eisenstein series provides a kernel yielding products of the periods of Hecke eigenforms at critical values. Extending this idea leads to a new type of Eisenstein series built with a double sum. We develop the properti... Read More about Kernels for products of L-functions.
