PROPERTY (m) FOR BOUNDED LINEAR OPERATORS
A bounded linear operator T acting on a Banach space satisfies property (m) if σ (T) \ σ ub(T) = E0(T), where σub(T) is the upper semi-Browder spectrum of T, σ(T) is the usual spectrum of T and E0(T) is the set of isolated points of the spectrum σ(T) of T which are eigenvalues of finite multiplicity. In this paper we introduce and study new properties (m), and (gm), which are related to Weyl type theorems. These properties are also studied in the framework of polaroid operators. |

NONUNIFORM WAVELET PACKET BASES FOR THE SPACES Lp(R) AND H1(R)
In this paper, we prove the results on the existence of unconditional nonuniform wavelet packet bases for the spaces Lp(R); 1 < p < ∞ and H1(R) based on the approach similar to that of Meyer and Coifman. Certain results are obtained in this direction by assuming only that the nonuniform wavelet packets ωn and its derivatives ώn have a common radial decreasing L1–majorant function. |

A FIXED
POINT
THEOREM
IN
INTUITIONISTIC
FUZZY
METRIC
SPACE
In this
paper,
we prove
a common
fixed
point
theorem
for
occasionally
weakly
compatible
mappings
in
intuitionistic
fuzzy
metric
space.
An
example
is
furnished
to
support
our main
result.
Our
results
improve
the
results
of
Sharma
and
Deshpande
[Common
fixed
point
theorems
for
finite
number
of
mappings
without
continuity
and
compatibility
on
intuitionistic

metric
spaces,

and
generalize
several
known
results
existing
in the
literature.

COUPLED
FIXED POINT
THEOREMS FOR
COMPATIBLE
MAPS AND ITS
VARIANTS IN
FUZZY METRIC
SPACES
In this
note, first
we introduce
the notion
of common
coupled
coincidence
point for
pairs of
mappings and
secondly, we
introduce
the variants
of
compatible
maps
(compatible
map of type
(A) and type
(P)) in
fuzzy metric
spaces for
coupled
maps. At the
end, we
prove some
common fixed
point
theorems for
pairs of
maps that
generalize
the results
of various
authors
present in
literature. |

SOME
WELL
KNOWN
INEQUALITIES
AND ITS
APPLICATIONS
IN
INFORMATION
THEORY
Inequalities
are very
useful
to
information
theory
for new
results.
Inequalities
are
widely
used for
some
bounds
of
information
divergence
measure
of in
Information
Theory.
There
are many
information
and
divergence
measures
exists
in the
literature
on
information
theory
and
statistics.
In this
paper we
establish
some
bounds
of
information
and
divergence
measures
using
some
inequalities
and
Csiszar’s
f-divergence
measure. |
