A Lipschitz condition along a transversal foliation implies local uniqueness for ODEs
J. Ángel Cid, F. Adrián F. Tojo
We prove the following result: if a continuous vector field is Lipschitz when restricted to the hypersurfaces determined by a suitable foliation and a transversal condition is…
A non-variational approach to the existence of nonzero positive solutions for elliptic systems
José Ángel Cid, Gennaro Infante
We provide new results on the existence of nonzero positive weak solutions for a class of second order elliptic systems. Our approach relies on a combined use of iterative techniqu…
New results for the Liebau phenomenon via fixed point index
José Ángel Cid, Gennaro Infante, Milan Tvrdý +1
We prove new results regarding the existence of positive solutions for a nonlinear periodic boundary value problem related to the Liebau phenomenon. As a consequence we obtain new…
Integration by parts and by substitution unified, Green's Theorem and uniqueness for ODEs
J. A. Cid, Rodrigo López Pouso
We present a rather unknown version of the change of variables formula for non-autonomous functions. We will show that this formula is equivalent to Green's Theorem for regions of…
