Existence of Solution for a Katugampola Fractional Differential Equation Using Coincidence Degree Theory [PDF]
Mediterranean Journal of MathematicsAbstractIn this paper, the authors study the existence of positive solutions to the fractional boundary value problem at resonance $$\begin{aligned} -(D^{\alpha ,\rho }_{a+}x)(t)= & {} f(t,x(t),D^{\alpha -1, \rho }_{a+}x(t)), \ \ t\in (a,b), \\ x(a)= & {} 0, \ \ x(b)=\int _{a}^{b} x(t){\text {d}}A(t), \end{aligned}$$

Turkish Journal of MathematicsIn this paper, the authors studied a boundary value problem for Hadamard fractional differential equations at resonance. By using the Mawhin's coincidence degree theory, they established an existence result for the problem under some conditions. They also presented an example to illustrate their result.

Four positive periodic solutions of a discrete time Lotka-Volterra competitive system with harvesting terms [PDF]
Opuscula Mathematica, 2011 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.
