ON
QUASIEINSTEIN WARPED PRODUCTS
In
this paper we investigate when an warped product manifold is a
quasiEinstein manifold and we give the expressions of the Ricci
tensors and scalar curvatures for the bases and fibres. In some
cases we give some obstructions to the existence of such
manifolds.

M^{k}TYPE ESTIMATES FOR MULTILINEAR COMMUTATOR OF
SINGULAR INTEGRAL OPERATOR ON SPACE OF HOMOGENEOUS TYPE
In
this paper, we prove the Mktype inequality for multilinear
commutator related to singular integral operator on space of
homogeneous type. By using the Mktype inequality, we obtain the
weighted Lpnorm inequality and the weighted estimates on the
generalized Morrey spaces for the multilinear commutator.

SUM OF GFRAMES IN HILBERT SPACES
We
consider the sum of finite number of gframes for a Hilbert
space H and observed that their sum need not be a gframe. A
necessary and sufficient condition for the sum of two gframes
to be a gframe has been obtained. Also, we study the sum of
finite number of gBessel sequences and obtained some results
regarding sum of gBessel sequences.

AN INFINITE DIMENSIONAL LESLIE MATRIX IN THE BANACH SPACE
c_{0}
**
In
this paper, we introduce Leslie matrix with an infinite
dimensional components. The top row { n} and sub diagonal
{w n} of such matrix are assumed to be elements of the
Banach space c_{0} .We prove that an infinite
dimensional Leslie matrices have a positive real eigenvalue. In
addition such matrix defines a compact linear operator from c_{0}
into c_{0}.

SUB COMPATIBLE AND AND SUB SEQUENTIAL CONTINUOUS MAPS IN
NONARCHIMEDEAN MENGER PM  SPACE
The aim of this paper is to establish some fixed point results
by using the new concepts of sub compatibility and sub
sequential continuity in non Archimedean Menger PMspaces (
Briefly, N. A. Menger PMspaces).
