A closed subset M of a Banach space E is epi-Lipschitzian, i.e., can be represented locally as the epigraph of a Lipschitz function, if and only if it is the level set of some locally Lipschitz function f : E β R, for which Clarke's generalized gradient does not contain 0 at points in the boundary o

β¦ Synopsis
The paper is devoted to the study of the so-called compactly epi-Lipschitzian sets. These sets are needed for many aspects of generalized di erentiation, particulary for necessary optimality conditions, stability of mathematical programming problems and calculus rules for subdi erentials and normal cones. We present general conditions under which sets deΓΏned by general constraints are compactly epi-Lipschitzian. This allows us to show how the compact epi-Lipschitzness properties behave under set intersections.

## Abstract We define a class of soβcalled β(__n__)βsets as a natural closure of recursively enumerable sets __W__~n~ under the relation βββ and study its properties.
In a previous paper, a certain class of discrete partially ordered sets was defined and a number of general properties of the sets was described. It was claimed that a kind of pre-geometry might be established on the basis of these definitions. To support this idea, it was asserted that a probabilit
