Holomorphically proyective Killing fields with vectorial fields associated in kahlerian manifolds
No full textTaking into account the harmonic and scalar curvatures in the study of Killing transformations between spacial complex (Einstenian, Peterson-Codazzi, Recurrent) and kaehlerian M spaces with almost complex J structure, we prove that there exists an holomorphically proyective transformation between M spaces and complex spaces
Algebraic properties and examples of inverse semigroups
No full textIn this paper mainly we have obtained some important algebric properties of inverse semigroups
On the local convergence of a midpoint method in banach spaces under a gamma-type condition
No full textIn this study we are concerned with the problem of approximating a locally unique solution of an operator equation in a Banach space setting using the midpoint method, introduced by us in [5], [6]. Here, we use gamma-type condition to provide a local convergence analysis. Our results compare favorably with the relevant ones in [9], [11], [12]-[14]- In particular our radius of convergence is larger. Numerical examples are also provided
Finitistic spaces in L-topological spaces
No full textIn this paper the concept of finitistic spaces in L-topological spaces is introduced by means of α-Q-covers of open L subsets. Also a characterization of finitistic spaces in the weakly induced L-topological spaces is obtained. Moreover the behavior of finitistic spaces under various types of maps such as fuzzy perfect maps is also investigated
On Triple sequence space of Bernstein operator of Rough I- convergence pre-cauchy sequences
No full textWe introduce and study some basic properties of rough I- convergentpre-Cauchy sequences of triple sequence of Bernstein polynomials and also study the set of all rough I- limits of a pre-Cauchy sequence of triple sequence of Bernstein polynomials and relation between analytic ness and rough I- statistical convergence of pre-Cauchy sequence of a triple sequences of Bernstein polynomials
On fractional powers of double band matrices
No full textIn the present article, we determine the explicit formula for finding the fractional powers of a double band matrix and in particular, we establish the formula for finding thenth root of the matrix. Some examples are also given for supporting the new formulas
Bipolar Fuzzy Hilbert Algebras
No full textThe notions of bipolar fuzzy subalgebras and bipolar fuzzy ideals of Hilbert algebras are introduced and studied in this work.There are given relationships between a bipolar fuzzy subalgebra and a bipolar fuzzy ideal.The characterizations of a bipolar fuzzy ideal are described, as well as a requirement for a bipolar fuzzy subalgebra to be a bipolar fuzzy ideal.The concept of equivalence relations on the family of all bipolar fuzzy ideals is explored, as well as certain associated features

No full textOn the parameters of symmetric difference bipartite graphs
No full text
The minimum degree Wiener index of a graph is the sum of distances between all unordered pairs of vertices with minimum degree in . In this paper, we computed minimum degree Wiener index of wheel graphs, molecular graphs of graphene, oxide network etc.
A class of bipartite irregular graphs named symmetric difference bipartite graph, , is defined with two disjoint vertex partitions containing -element subsets and containing -element subsets and -element subsets of , for .
An edge between a vertex and a vertex exists if their symmetric difference has exactly elements. We determined various graph theoretic properties of symmetric difference bipartite graphs and compared its topological indices with other families of graphs
