\(p\)-adic \(L\)-functions for base change lifts of \(\mathrm{GL}_ 2\) to \(\mathrm{GL}_ 3\). (English) Zbl 0705.11033

The author constructs a two-variable \(p\)-adic \(L\)-function which \(p\)-adically interpolates critical values of the symmetric square \(L\)-functions attached to cusp forms of integral weights. The proof uses generalization to the case of half-integral weight of the author’s results on \(p\)-adic modular forms of integral weight and \(p\)-adic Hecke algebras and the method of \(p\)-adic Rankin convolutions as developed by the author [cf. Invent. Math. 79, 159–195 (1985; Zbl 0573.10020); Ann. Inst. Fourier 38, No. 3, 1–83 (1988; Zbl 0645.10028)]. To prove that the \(L\)-functions obtained are holomorphic an idea of C.-G. Schmidt [Invent. Math. 92, 597–631 (1988; Zbl 0656.10023)] is adopted.
