L-FUZZY GRADATION OF OPENNESS AND L-FUZZY GRADATION OF PROXIMITY
Mondal Taras Kumar ; Samanta S.K. ;
The Pure and Applied Mathematics, volume 13, issue 2, 2006, Pages 71~94
In this paper we study lattice valued fuzzy gradation of openness so that fuzzy gradation of openness  could be obtained as a particular case. Some of its properties are studied. We also give definitions of lattice valued graded fuzzy filters, graded, fuzzy grills, graded fuzzy preproximities and proximities.

In , we have recently proved that an additive inverse semiring S is a Clifford semifield if and only if S is a subdirect product of a field and a distributive lattice. In this paper, we study the matrix semiring over a Clifford semifield.
P(R,M) GAMMA NEAR-RINGS
Cho Yong-Uk ; Chelvam T.Tamizh ; Meenakumari N. ;
The Pure and Applied Mathematics, volume 13, issue 2, 2006, Pages 113~120
In this paper, we introduce the concept of P(r,m)
-near-ring and obtain some characterization of P(r,m)
-near-rings through regularity conditions.
A HYBRID VOLTERRA-TYPE EQUATION WITH TWO TYPES OF IMPULSES
Belbas S.A. ; Park Jong-Seo ;
The Pure and Applied Mathematics, volume 13, issue 2, 2006, Pages 121~136
We formulate and analyze a hybrid system model that involves Volterra integral operators with multiple integrals and two types of impulsive terms. We give a constructive proof, via an iteration method, of existence and uniqueness of solutions.
ON GENERALIZATION OF COVARIANCE AND VARIANCE
Lin C.S. ;
The Pure and Applied Mathematics, volume 13, issue 2, 2006, Pages 137~149
We introduce the notion of the generalized covariance and variance for bounded linear operators on Hilbert space, and prove that the generalized covariance-variance inequality holds. It turns out that the inequality is a useful formula in tile study of inequality involving linear operators in Hilbert spaces.
HYPERBOLIC CURVATURE AND K-CONVEX FUNCTIONS
Song Tai-Sung ;
The Pure and Applied Mathematics, volume 13, issue 2, 2006, Pages 151~155
curve in the open unit disk
. Flinn and Osgood proved that
if and only if the curve
is convex for every convex conformal mapping
denotes the hyperbolic curvature of
at the point z. In this paper we establish a generalization of the Flinn-Osgood characterization for a curve with the hyperbolic curvature at least 1.
WEAKLY B-REGULAR NEAR-RINGS
Chelvam Thirugnanam Tamizh ; Cho Yong-Uk ;
The Pure and Applied Mathematics, volume 13, issue 2, 2006, Pages 157~165
The notion of regularity in near-ring was generalized by the concept of b-regular and some characterizations of the same was obtained through the substructures viz bi-ideals in near-rings. In this paper, we generalize further and introduce tile notion of weakly b-regular near-rings and obtain a characterization of tile same.
