Coincidence Points in Generalized Metric Spaces [PDF]
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.

Chen-Nester-Tung quasi-local energy and Wang-Yau quasi-local mass
In this paper, we show that the Chen-Nester-Tung (CNT) quasi-local energy is closely related to the Wang-Yau (WY) quasi-local mass. As a particular example, we compute the second variation of the CNT quasi-local energy for axially symmetric Kerr-like ...

Variation of Fixed-Point and Coincidence Sets [PDF]
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.

Leibniz Equivalence. On Leibniz's (Bad) Influence on the Logical Empiricist Interpretation of General Relativity [PDF]
Einstein’s “point-coincidence argument'” as a response to the “hole argument” is usually considered as an expression of “Leibniz equivalence,” a restatement of indiscernibility in the sense of Leibniz.

Superconductivity in CeCoIn5-xSnx: Veil Over an Ordered State or Novel Quantum Critical Point?
Measurements of specific heat and electrical resistivity in magnetic fields up to 9 T along [001] and temperatures down to 50 mK of Sn-substituted CeCoIn5 are reported. The maximal -ln(T) divergence of the specific heat at the upper critical field H_{c2}

Tripled Coincidence Points of Mappings in Partially Ordered 0-Complete Partial Metric Spaces
In this paper, we introduce the concept of a tripled coincidence point for a pair of nonlinear contractive mappings F : X3 → X and g : X → X in partially ordered 0-complete partial metric spaces and obtain existence and uniqueness theorems.

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

Coincidence points of two maps
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]
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.

Theory of photon coincidence statistics in photon-correlated beams [PDF]
The statistics of photon coincidence counting in photon-correlated beams is thoroughly investigated considering the effect of the finite coincidence resolving time. The correlated beams are assumed to be generated using parametric downconversion, and the
