    Existence principles for singular vector nonlocal boundary value problems with \(\phi\)-Laplacian and their applications (English)
    0 references
    The paper establishes existence principles for the solutions of singular differential systems of \(\phi\)-Laplacian type NEWLINE\[NEWLINE\phi(u')' = f(t,u,u')NEWLINE\]NEWLINE under nonlocal boundary conditions. The nonlinearity \(f\) may be singular in the state variables. Under appropriate growth conditions, an existence result is obtained via the regularization technique and the Leray-Schauder degree theory.
