The Riemann Zeta Function's first zero is about 1/2+14.13472i. Does any other L-function go as far without vanishing?
Why is the discrete spectrum of the laplacian on SL(68,Z)\SL(68,R)/SO(68,R) different than on lower-rank quotients?
We apply the positivity method of Stark-Odlyzko-Serre-Poitou-Mestre et al to these and other problems about automorphic forms on SL(n,Z)\SL(n,R)/SO(n,R).

Note: there are 15 figures, so the files are large. Also, the pictures may not appear correctly in the .dvi versions, so the pdf or postscript files are heavily recommended.
