Coincidence Points in Generalized Metric Spaces [PDF]

open access: yesSet-Valued and Variational Analysis, 2014
Covering mappings in generalized metric spaces are considered. The coincidence points theorems for single-valued and set-valued mappings are proved. The results obtained are applied to the problem of solvability of equations in the space of continuous functions. © 2014, Springer Science+Business Media Dordrecht.

Configuration-like spaces and coincidences of maps on orbits

open access: yes, 2010
In this paper we study the spaces of $q$-tuples of points in a Euclidean space, without $k$-wise coincidences (configuration-like spaces). A transitive group action by permuting these points is considered, and some new upper bounds on the genus (in the ...

The dimensionless age of the Universe: a riddle for our time

open access: yes, 2016
We present the interesting coincidence of cosmology and astrophysics that points toward a dimensionless age of the universe H_0*t_0 that is close to one.

Variation of Fixed-Point and Coincidence Sets [PDF]

open access: yesJournal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1988
AbstractTopologise the set of continuous self-mappings of a Hausdorff space by the graph topology. When the set of closed subsets of the space is given the upper semi-finite topology then the function which assigns to a map its fixed-point set is continuous. In many familiar cases this is the largest such topology.

Energy and angular momentum sharing in dissipative collisions

open access: yes, 1999
Primary and secondary masses of heavy reaction products have been deduced from kinematics and E-ToF measurements, respectively, for the direct and reverse collisions of 93Nb and 116Sn at 25 AMeV.

Some remarks on the attractor behaviour in ELKO cosmology

open access: yes, 2014
Recent results on the dynamical stability of a system involving the interaction of the ELKO spinor field with standard matter in the universe have been reanalysed, and the conclusion is that such system does not exhibit isolated stable points that could ...

Coincidence points of two maps

open access: yesFunctional Analysis and Its Applications, 2014
The problem of finding coincidence points of two maps is studied. An iteration method for approximately solving this problem is suggested. © 2014 Springer Science+Business Media New York.

The least number of coincidence points on surfaces [PDF]

open access: yesJournal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1995
AbstractBo Ju Jiang introduced an invariant lying in the braid group which is the best lower bound of the number of fixed points in a homotopy class of a given pair of self maps of a surface. Here we modify this construction to get a lower bound of the number of coincidence points of a pair of maps between two closed surfaces.

COINCIDENCE POINTS OF COMPATIBLE MULTIVALUED MAPPINGS

open access: yesDemonstratio Mathematica, 1996
Let \(CB(X)\) be the space of nonempty bounded closed subsets of a metric space \((X,d)\) with the Hausdorff metric. Mappings \(T:X\to CB(X)\), \(f:X\to X\) are said to be compatible if, for any sequence \(\{x_n\}\subset X\) satisfying \(\lim_{n\to\infty} fx_n\in \lim_{n\to\infty} Tx_n\) we have \(\lim_{n\to\infty} H(fTx_n,Tfx_n)=0\).
