| Outline of Final Research Achievements |
We studied Theta functions (Yoshida lifts, Harris-Soudry-Taylor (HST) lifts) and special values of L-functions. By using an explicit inner product formula, which was obtained in our previous research, we showed that a non-vanishing result of special values of twisted Rankin-Selberg type L-functions which is associated with Hilbert modular forms over real quadratic fields under some assumptions.
We also studied an explicit relation Bessel periods and special values of L-functions, which is a generalization of our previous result. An explicit result is not yet available, however, we find a formulation which is an analogue of Yoshida lifts case.
