3. A FIXED POINT PRINCIPLE FOR SOME NONSELF OPERATORS ON LARGE KASAHARA SPACES.

Author

OLARU, ION MARIAN

Subjects
*METRIC spaces, *FUNCTION spaces, *OPERATOR functions, *MATHEMATICS, *DIAMETER
Abstract

In this paper we give a saturated fixed point principle for nonself operators on a large Kasahara space. Our results extend some results given by I.M Olaru and N.A. Secelean in A New Approach of Some Contractive Mappings on Metric Spaces, Mathematics, 2021 9(12). [ABSTRACT FROM AUTHOR]

12. Common fixed point results in b-cone metric spaces over topological vector spaces.

Author

Olaru, Ion Marian, Branga, Adrian, and Oprea, Anca

Subjects
*FIXED point theory, *TOPOLOGICAL spaces, *VECTOR spaces, *METRIC spaces, *BANACH spaces, *CONTRACTIONS (Topology)
Abstract

In this paper we introduce the notion of b-cone metric space over topological vector space (for short b-TVS cone metric space) and prove some common fixed point theorems in complete b-cone metric spaces over topological vector spaces. These results generalize, extend and unify several well-known recent related results in literature. [ABSTRACT FROM AUTHOR]

14. DATA DEPENDENCE FOR SOME INTEGRAL EQUATIONS.

Author

Olaru, Ion Marian

Subjects
LINEAR dependence (Mathematics), INTEGRAL equations, FUNCTIONAL analysis, FUNCTIONAL equations, FIXED point theory, FUNCTION spaces
Abstract

In the paper Integral equations, periodicity and fixed points, published in Fixed Point Theory, 9(2008), No 1, 47-65 the author T.A. Burton considered the equation x(t) = g(t) +∫t-∞K(t, s, x(s))ds. In this paper we shall study the data dependence for this integral equations. [ABSTRACT FROM AUTHOR]
