Geometric and homotopy theoretic methods in Nielsen coincidence theory
, 2006 In classical fixed point and coincidence theory the notion of Nielsen numbers has proved to be extremely fruitful. Here we extend it to pairs (f_1, f_2) of maps between manifolds of arbitrary dimensions. This leads to estimates of the minimum numbers MCC(

Continuous Dependence of Coincidence Points on a Parameter
Set-Valued and Variational Analysis, 2014 In the paper, the authors consider the coincidence points existence problem with a parameter in metric spaces. They give sufficient conditions for the dependence of a coincidence point on the parameter to be continuous, Hölder continuous, or Lipschitz continuous.

Nonstabilized Nielsen coincidence invariants and Hopf--Ganea homomorphisms
, 2006 In classical fixed point and coincidence theory the notion of Nielsen numbers has proved to be extremely fruitful. We extend it to pairs (f_1,f_2) of maps between manifolds of arbitrary dimensions, using nonstabilized normal bordism theory as our main ...

Some results on coincidence points [PDF]
Bulletin of the Australian Mathematical Society, 1999 In this paper we prove some coincidence point theorems for nonself single-valued and multivalued maps satisfying a nonexpansive condition. These extend fixed point theorems for multivalued maps of a number of authors.

Coincidence Points of Weaker Contractions in Partially Ordered Metric Spaces
Journal of Applied Mathematics, 2013 We prove new coincidence point theorems for the -contractions and generalized Meir-Keeler-type --contractions in partially ordered metric spaces. Our results generalize many recent coincidence point theorems in the literature.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

On almost coincidence points in generalized convex spaces
Fixed Point Theory and Applications, 2006 We prove an almost coincidence point theorem in generalized convex spaces. As an application, we derive a result on the existence of a maximal element and an almost coincidence point theorem in hyperconvex spaces.

On Approximate Coincidence Point Properties and Their Applications to Fixed Point Theory
Journal of Applied Mathematics, 2012 We first establish some existence results concerning approximate coincidence point properties and approximate fixed point properties for various types of nonlinear contractive maps in the setting of cone metric spaces and general metric spaces.

, 2016 Studying event time series is a powerful approach for analyzing the dynamics of complex dynamical systems in many fields of science. In this paper, we describe the method of event coincidence analysis to provide a framework for quantifying the strength ...

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our
