%0 Journal Article %T Functoriality and special values of L-functions %A A. Raghuram %A Freydoon Shahidi %J Mathematics %D 2007 %I arXiv %X This is a semi-expository article concerning Langlands functoriality and Deligne's conjecture on the special values of $L$-functions. The emphasis is on symmetric power $L$-functions associated to a holomorphic cusp form, while appealing to a recent work of Mahnkopf on the special values of automorphic $L$-functions. %U http://arxiv.org/abs/0707.1335v1
