Weakly coupled two slow- two fast systems, folded node and mixed mode oscillations
, 2013 We study Mixed Mode Oscillations (MMOs) in systems of two weakly coupled slow/fast oscillators. We focus on the existence and properties of a folded singularity called FSN II that allows the emergence of MMOs in the presence of a suitable global return ...

Existence and location results for the bending of an elastic beam
, 2007 In this paper it is obtained an existence and location result for some fourth order fully nonlinear equation with Lidstone boundary conditions. The nonlinearity verifies a Nagumo-type condition without assumptions of bound type and monotonicity ...

On Variational Inequalities with Multivalued Perturbing Terms Depending on Gradients
, 2020 In this paper, we study variational inequalities of the form {⟨A(u),v-u⟩+⟨F(u),v-u⟩+J(v)-J(u)≥0,∀v∈Xu∈X,where A and F are multivalued operators represented by integrals, J is a convex functional, and X is a Sobolev space of variable exponent.

Location results: an under used tool in higher order boundary value problems [PDF]
, 2009 The method of lower and upper solutions provides, as well as residts of existence, other important properties such as location of solution, extremal solutions,..., which have been under used and, moreover, its potential has not been optimized, either in ...

Multiple solutions for systems of differential equations with nonlinear boundary conditions
, 2011 We establish the existence of three solutions in admissible bounding sets for systems of nonlinear differential equations of the form y'' = f (x;y;y'), x Ie ∈ [0;1] satisfying the fully nonlinear boundary conditions g((y(0);y(1)); (y'(0);y'(1))) = 0: We ...
