Abstract. In this note, we provide an adaptation of the Kohler-Jobin rearrangement technique to the setting of the Gauss space. As a result, we prove the Gaussian analogue of the Kohler-Jobin’s resolution of a conjecture of PólyaSzegö: when the Gaussian torsional rigidity of a (convex) domain is fixed, the Gaussian principal frequency is minimized for the half-space. At the core of this rearrangement technique is the idea of considering a “modified” torsional rigidity, with respect to a given…

Abstract. We determine all of the cases of equality in a recent inequality of Bobkov that implies the isoperimetric inequality on Gauss space. As an application we determine all of the cases of

The parser, especially its mapping rule interpreter, used in KBMT-89 is described, characterized by its ability to produce semantic and syntactic structures of a parse simultaneously and therefore more efficiently than other kinds of analyzers.
