A
Generalization
of Slant
Toeplitz
Operators
We ask about
the
solutions of
the equation
λM_{z}X = XM_{z2},
for general
complex
number
λ,
which are
referred as
λslant Toeplitz
operators.
We
completely
solve this
equation and
discuss some
algebraic as
well as
spectral
properties
of λslant Toeplitz
operators.
The
compactness
of the
compression
of
λslant Toeplitz
operators is
also
addressed.

Hopf
Bifurcation
Analysis
in a
System
for
Cancer
Virotherapy
with
Effect
of
the
Immune
System
We
consider
a
system
of
differential
equations
which
is
motivated
biologically
and
simulates
a
cancer
virotherapy.
The
existence
of
equilibrium
points
and
their
local
stability
are
studied
using
the
characteristic
equation.
We
investigate
Hopf
bifurcation
around
the
interior
equilibrium
point.

Further Results on the Uniqueness of Meromorphic Functions and their Derivative Counterpart Sharing One or Two Sets
In this
paper we
prove a
number
of
results
concerning
uniqueness
of a
meromorphic
function
as well
as its
derivative
sharing
one or
two
sets. In
particular,
we deal
with the
specific
question
raised
in [18],
[19],
[20] and
ultimately
improve
the
result
of Banerjee  Bhattacharjee
[4].

Soft
Group
Based on
Soft
Element
Using the
notion of
soft element
[13], in
this paper,
we de ne a
binary
operation on
the set of
all nonempty
soft
elements of
a given soft
set to
introduce
soft
groupoid.
Then we give
the
definition
of soft
group based
on soft
elements and
establish
necessary
and
sufficient
conditions
for a soft
set to be a
soft group.
Also we
compare some
properties
like
commutative
property,
cyclic
property of
soft group
with those
of given
parameter
set and
initial
universe
set.

Neighborhood of a Class of Analytic Functions with Negative Coefficients Defined by the Generalized Ruschewey Derivatives Involving a General Fractional Derivative Operator
By making use of the familiar concept of neighborhoods of analytic functions, we prove several inclusion relations associated with the (n, δ)  neighborhoods of various subclasses of starlike and convex functions of complex order defined by the generalized Ruscheweyh derivative involving a general fractional derivative operator. Special cases of some of these inclusion relations are shown to yield known results.
