Nonconvex, lower semicontinuous piecewise linear optimization. Discrete Optimization
, 2008 A branch-and-cut algorithm for solving linear problems with continuous separable piecewise linear cost functions was developed in 2005 by Keha et. al. This algorithm is based on valid inequalities for an SOS2 based formulation of the problem.

On a theorem of Baire about lower semicontinuous functions [PDF]
, 2008 A theorem of Baire concerning the approximation of lower semicontinuous real valued functions defined on a metric space, by increasing sequences of continuous functions is extended to the "nonsymmetric" case, i.e.

Saddle point theorems on generalized convex spaces
Journal of Inequalities and Applications, 2000 A sharpened extension of Komiya's saddle point theorem is obtained for generalized convex spaces. Moreover, we show that convexity of the involved sets in his theorem can be replaced by acyclicity, and continuity of the involved functions by lower and ...

Nonlocal Conditions for Lower Semicontinuous Parabolic Inclusions
, 2011 We discuss conditions for the existence of at least one solution of a discontinuous parabolic equation with lower semicontinuous right hand side and a nonlocal initial condition of integral type.

Separating sets by lower and upper semicontinuous functions with a closed graph
, 2016 In this paper we characterize the pairs (A- ;A+) of disjoint subsets of perfectly normal topological space which can be separated by a lower and an upper semicontinuous function with a closed graph.Mathematics Subject Classification (2010): 54C30, 26A15,

Semicontinuous maps on module varieties
We study semicontinuous maps on varieties of modules over finite-dimensional algebras. We prove that truncated Euler maps are upper or lower semicontinuous. This implies that g-vectors and E-invariants of modules are upper semicontinuous. We also discuss
