Multiplicity of solutions for the Minkowski-curvature equation via shooting method

open access: yesBruno Pini Mathematical Analysis Seminar, 2019
In this paper we prove the existence and the multiplicity of radial positive oscillatory solutions for a nonlinear problem governed by the mean curvature operator in the Lorentz-Minkowski space. The problem is set in an N-dimensional ball and is subject to Neumann boundary conditions. The main tool used is the shooting method for ODEs.

Enlarging the domain of convergence for multiple shooting by the homotopy method [PDF]

open access: yesNumerische Mathematik, 1980
The homotopy method is a frequently used technique in overcoming the local convergence nature of multiple shooting. In this paper sufficient conditions are given that guarantee the homotopy process to be feasible. The results are applicable to a class of two-point boundary value problems.
