The inverse problems for motions of dynamic systems of which are described by system of the ordinary differential equations are examined. The classification of
In this paper, we determine the second Hochschild cohomology group for a class of self-injective algebras of tame representation type namely, which are standard
Let E be an elliptic curve over a given number field . By Mordell’s Theorem, the torsion subgroup of E defined over Q is a finite group. Using Lutz-Nagell Theo
We consider plus-operators in Krein spaces and generated operator linear fractional relations of the following form: . We study some special type of factorizati
In this paper, we introduce a new class of b-open sets called Bc-open, this class of sets lies strictly between the classes of θ-semi open and b-open sets. We
