For domains in,, we prove universal upper and lower bounds on the product of the bottom of the spectrum for the Laplacian to the powerand the supremum over all starting points of the-moments of the exit time of Brownian motion. It is shown that the lower bound is sharp for integer values ofand that for, the upper bound is asymptotically sharp as. For all, we prove the existence of an extremal domain among the class of domains that are convex and symmetric with respect to all coordinate axes. For this class of domains we conjecture that the cube is extremal. References
