Sub-exponential decay of operator kernels 
 for functions of generalized Schr\"odinger operators
(294K, .ps)

ABSTRACT.  We study the decay at large distances of operator kernels of functions 
 of generalized Schr\"odinger operators. We prove sub-exponential decay for functions in Gevrey classes and exponential decay for real analytic functions.
