✦ Synopsis

Abstract

After introducing the notion of BPS preons as the basic constituents of M‐theory, we discuss the recent negative results in the search for solutions of the D = 10 and D = 11 supergravity equations preserving 31/32 supersymmetries i.e., of preonic solutions. The absence of these supergravity preonic solutions may point out to a pure quantum nature of BPS preons, manifesting itself in the need of incorporating quantum (stringy/M‐theoretic) corrections to the supergravity equations.

## Abstract We present a pedagogical discussion of the emergence of gauged supergravities from M‐theory. First, a review of maximal supergravity and its global symmetries and supersymmetric solutions is given. Next, different procedures of dimensional reduction are explained: reductions over a toru
