On Lower Semicontinuity of Integral Functionals. II
SIAM Journal on Control and Optimization, 1977A necessary and sufficient condition for the integral functional $I(x( \cdot ),y( \cdot )) = \smallint _G f(t,x(t),y(t))d\mu $ to be sequentially lower semicontinuous with respect to some kinds of strong convergence of $x( \cdot )$components and weak convergence of $y( \cdot )$-components is proved.

On the Cone of Bounded Lower Semicontinuous Functions
Mathematical Notes, 2005For a topological space \(X\), let \(BC(X)\) be the Banach space of all bounded, real-valued continuous functions on \(X\), endowed with the ordinary addition and multiplication and the partial order: \[ f_1\geq f_2\quad\text{iff }f_1(x)\geq f_2(x)\quad\text{for all }x\in X, \] and the sup-norm \(\| f\|= \sup\{|f(x)|: x\in X\}\). \(BC(X)_\sim\) denotes

Lower Semicontinuous Convex Functions
2011The theory of convex functions is most powerful in the presence of lower semicontinuity. A key property of lower semicontinuous convex functions is the existence of a continuous affine minorant, which we establish in this chapter by projecting onto the epigraph of the function.

L 2-lower semicontinuity of functionals of quadratic type
Annali di Matematica Pura ed Applicata, 1981A representation formula for the L2-lower semicontinuous envelope of a quadratic integral of Calculus of Variations is given. Some particular cases are explicited in the details.

Lower Semicontinuous Increasing Functionals
1993In this chapter we study some properties of the functionals F(x,A) which are lower semicontinuous with respect to x and increasing with respect to A.

Lower semicontinuous convex functions
1989Our differentiability results for convex functions made heavy and consistent use of continuity, but in both theoretical and applied aspects of convex functions, it is sometimes desirable to weaken this hypothesis. Lower semicontinuity is precisely what is needed.

Points of Upper and Lower Semicontinuity for Multivalued Functions
Ukrainian Mathematical Journal, 2018It is known that a multifunction of two variables $F:X\times Y\to Z$, whose $X$ and $Y$ sections are both lower (resp. upper) semicontinuous may be (under usual assumptions on $X$, $Y$, $Z$) non weakly measurable (resp. nonmeasurable), but if the $X$-sections are lsc, the $Y$-sections are usc and the values are compact, it belongs to the upper Borel ...
