چکیده

Let π be a cuspidal, automorphic representation of GSp4 attached to a Siegel modular form of degree 2. We refine the method of Furusawa [9] to obtain an integral representation for the degree-8 L-function L(s, π × τ), where τ runs through certain cuspidal, automorphic representation of GL2. Our calculations include the case of square-free level for the p-adic components of τ , and a wide class of archimedean types including Maaß forms. As an application we obtain a special value result for L(s, π × τ).

We give a narrow zero-free region for standard L-functions on GL(n) and Rankin-Selberg L-functions on GL(m) × GL(n) through the use of positive Dirichlet series. Such zero-free regions are equivalent to lower bounds on the edge of the critical strip, and in the case of L(s, π × ˜ π), on the residue at s = 1. Using the latter we show that a cuspidal automorphic representation on GL(n) is determi...

Let L (x, t) = 2H R t 0 δ(B s − x)s ds be the weighted local time of fractional Brownian motion B with Hurst index 1/2 < H < 1. In this paper, we use Young integration to study the integral of determinate functions R R f(x)L (dx, t). As an application, we investigate the weighted quadratic covariation [f(B), B ] ) defined by [f(B), B ] (W ) t := lim n→∞ 2H n−1

We discuss the questions related to dark energy in the Universe. We note that in spite of the effect of dark energy, large-scale structure is still being generated in the Universe and this will continue for about ten billion years. We also comment on some statements in the paper " Dark energy and universal antigravitation " by A.D. Chernin [4].
