    First order systems of odes with nonlinear nonlocal boundary conditions

    Get PDF
    In this article, we prove an existence of solutions for a non-local boundary value problem with nonlinearity in a nonlocal condition. Our method is based upon the Mawhin's coincidence theory

    A Classical Approach to Dynamics of Parabolic Competitive Systems

    Get PDF
    We study the reaction-diffusion system, its stationary solutions, the behavior of the system near them and discuss similarities and differences for different boundary conditions

    A note on Blasius type boundary value problems

    Get PDF
    The existence and uniqueness of a solution to a generalized Blasius equation with asymptotic boundary conditions is proved. A new numerical approximation method is proposed

    Second order systems with nonlinear nonlocal boundary conditions

    Get PDF
    This paper is concerned with the second order differential equation with not necessarily linear nonlocal boundary condition. The existence of solutions is obtained using the properties of the Leray鈥揝chauder degree. The results generalize and improve some known results with linear nonlocal boundary conditions
