Cosmological dynamics and observational constraints of an interacting early scalar field coupled to radiation
Dorian Araya, Felipe Herrera, Nelson Videla
We study the cosmic evolution of an interacting scalar field radiation model, in which a minimally coupled scalar field exchanges energy with the radiation sector through an expone…

On twisted Koecher-Maass series and its integral Kernel
Fernando Herrera
We establish the integral kernel associated with the Koecher-Maass series of degree three twisted by an Eisenstein series. We prove that such a kernel admits an analytic continuati…
