Some Properties of Mappings on Generalized Topological Spaces
This paper considers generalizations of open mappings, closed mappings,
pseudo-open mappings, and quotient mappings from topological spaces to
generalized topological spaces. Characterizations of these classes of mappings
are obtained and some relationships among these classes are established.Comment: 8 papge
Color Visualization of Blaschke Self-Mappings of the Real Projective Plan
The real projective plan can be endowed with a dianalytic structure
making it into a non orientable Klein surface. Dianalytic self-mappings of that
surface are projections of analytic self-mappings of the Riemann sphere
. It is known that the only analytic bijective
self-mappings of are the Moebius transformations. The
Blaschke products are obtained by multiplying particular Moebius
transformations. They are no longer one-to-one mappings. However, some of these
products can be projected on and they become dianalytic self-mappings of
. More exactly, they represent canonical projections of non orientable
branched covering Klein surfaces over . This article is devoted to color
visualization of such mappings. The working tool is the technique of
simultaneous continuation we introduced in previous papers.Comment: 16 pages, 5 pages of figure
Existence And Convergence Theorems For Multivalued Generalized Hybrid Mappings In Cat({\kappa})-Space
In this study, we give definition of some multivalued hybrid mappings which
are general than many mappings in the existing literature, then we give some
existence and convergence results for these mappings in CAT({\kappa})-space
Proper holomorphic mappings into -concave quadric domains in projective space
In this paper, we prove a type of partial rigidity result for proper
holomorphic mappings of certain -concave domains in projective space into
model quadratic -concave domains. The main technical result is a degree
estimate for proper holomorphic mappings into the model domains, provided that
the mappings extend to projective space as rational mappings, and the source
domain contains algebraic varieties and has a boundary with low CR complexity
Growth theorems in slice analysis of several variables
In this paper, we define a class of slice mappings of several Clifford
variables, and the corresponding slice regular mappings. Furthermore, we
establish the growth theorem for slice regular starlike or convex mappings on
the unit ball of several slice Clifford variables, as well as on the bounded
slice domain which is slice starlike and slice circular
On Harmonic -Bloch and -Bloch-type mappings
The aim of this paper is twofold. One is to introduce the class of harmonic
-Bloch-type mappings as a generalization of harmonic -Bloch mappings
and thereby we generalize some recent results of harmonic -Bloch-type
mappings investigated recently by Efraimidis et al. \cite{EGHV}. The other is
to investigate some subordination principles for harmonic Bloch mappings and
then establish Bohr's theorem for these mappings and in a general setting, in
some cases.Comment: 17 pages; Comments are welcom
The space of initial conditions for linearisable mappings
We apply the algebraic-geometric techniques developed for the study of
mappings which have the singularity confinement property to mappings which are
integrable through linearisation. The main difference with respect to the
previous studies is that the linearisable mappings have generically unconfined
singularities. Despite this fact we are able to provide a complete description
of the dynamics of these mappings and derive rigorously their growth
properties.Comment: 20 pages, 8 figure
Fibers of Polynomial Mappings Over Rn
We prove results on fibers of polynomial mappings Rn ! Rn and deduce when
such mappings are surjective under certain conditions
Starlikeness and convexity of polyharmonic mappings
In this paper, we first find an estimate for the range of polyharmonic
mappings in the class . Then, we obtain two characterizations in
terms of the convolution for polyharmonic mappings to be starlike of order
, and convex of order , respectively. Finally, we study the
radii of starlikeness and convexity for polyharmonic mappings, under certain
coefficient conditions
Best proximity point results for almost contraction and application to nonlinear differential equation
Brinde [Approximating fixed points of weak contractions using the Picard
itration, Nonlinear Anal. Forum 9 (2004), 43-53] introduced almost contraction
mappings and proved Banach contraction principle for such mappings. The aim of
this paper is to introduce the notion of multivalued almost -
contraction mappings and present some best proximity point results for this new
class of mappings. As applications, best proximity point and fixed point
results for weak single valued -contraction mappings are obtained. An
example is presented to support the results presented herein. An application to
a nonlinear differential equation is also provided
