Closures of faces of compact convex sets

A. K. Roy (1975)

Annales de l'institut Fourier

Similarity:

This paper gives necessary and sufficient conditions for the closure of a face in a compact convex set to be again a face. As applications of these results, several theorems scattered in the literature are proved in an economical and uniform manner.

Marginalization like a projection.

Juan Francisco Verdegay-López, Serafín Moral (2001)

Mathware and Soft Computing

Similarity:

This paper studies the problem of marginalizing convex polytopes of probabilities represented by a set of constraints. This marginalization is obtained as a special case of projection on a specific subspace. An algorithm that projects a convex polytope on any subspace has been built and the expression of the subspace, where the projection must be made for obtaining the marginalization, has been calculated.
