On D.c. functions and mappings
A number of new results on d.c. functions (i.e. functions which can be represented as the difference of two continuous convex functions) and on d.c. mappings is proved....

Spaces of d.c. Mappings on Arbitrary Intervals
M. Zippin (2000) obtained results on the structure of the Banach space of all d.c. functions on [0,1]. We give a generalization to the case of the space of all d.c. Banach space valued mappings. The case of d.c. ma...

On extensions of D.C. functions and convex functions
We prove results on extension of D.C. functions and mappings. We prove also two results on extendability of continuous convex functions from a closed subspace of a normed linear space....

Morse-Sard theorem for d.c. functions and mappings on R2./sup
If f is a d.c. function on R2 (i.e. f = f1 - f2, where f1, f2 are convex) and C of "planar variation" of (discontinuous) functions on R2. We present a similar complete proof based on the wellknown theory of BV functions...

Normal cycles and curvature measures of sets with d.c. boundary
We show that for every compact domain in a Euclidean space with d.c. (delta-convex) boundary there exists a unique Legendrian cycle such that the associated curvature measures fulfill a local version of the Gauss-Bonnet formula. This was kno...

Quotients of continuous convex functions on nonreflexive Banach spaces
function f such that 1/f is not a d.c. function (i.e., a difference of two continuous convex functions). This result together with known ones implies that X is reflexive if andonly if each everywhere defined quoti...

Double phase d.c. switching converter with inter-phase reactor
The principle of d.c.-d.c. switching converter is known. The parallel connection of two (or more) d.c. switching converters with shifted switching is multiple phase d.c. switching converter....
