On the standard L-function attached to quaternionic modular forms

In this paper we study the analytic properties of standard L-function attached to vector valued quaternionic modular forms using Rankin-Selberg method. This involves construction theta series, which obtain by applying some differential operators on Jacobi-theta series studied Krieg. Such are obtained from Howe-Weyl duality for pair Spn(C)×GL2n(C).
