Fixed point property and degree of coincidence [PDF]
We introduce the concept of degree of coincidence to measure the divergence from the fixed point property in case a space does not have the FPP.

Periodic solution of a bioeconomic fishery model by coincidence degree theory [PDF]
In this article we use coincidence degree theory to study the existence of a positive periodic solutions to the following bioeconomic model in fishery dynamics \begin{equation*}\label{eq1.3} \begin{cases} \frac{dn}{dt} = n \left(r(t) \left(1-\frac{n ...

Application of Mawhin′s Coincidence Degree and Matrix Spectral Theory to a Delayed System [PDF]
This paper gives an application of Mawhin’s coincidence degree and matrix spectral theory to a predator‐prey model with M‐predators and N‐preys. The method is different from that used in the previous work. Some new sufficient conditions are obtained for the existence and global asymptotic stability of the periodic solution.

Effect of Fracture Coincidence on Mechanical Properties and Damage Evolution of Sandstone [PDF]
To study the effect of fracture coincidence on mechanical properties and damage evolution of fractured sandstone, five kinds of sandstone specimens with different crack distributions were simulated by RFPA2D software under uniaxial compression test. The

Four positive periodic solutions of a discrete time Lotka-Volterra competitive system with harvesting terms [PDF]
In this paper, by using Mawhin's continuation theorem of coincidence degree theory, we establish the existence of at least four positive periodic solutions for a discrete time Lotka-Volterra competitive system with harvesting terms.
