Existence of Bistable Waves in a Competitive Recursion System with Ricker Nonlinearity [PDF]
, 2013 Using an abstract scheme of monotone semiflows, the existence of bistable traveling wave solutions of a competitive recursion system with Ricker nonlinearity is established. The traveling wave solutions formulate the strong inter-specific actions between

A General Backwards Calculus of Variations via Duality
, 2010 We prove Euler-Lagrange and natural boundary necessary optimality conditions for problems of the calculus of variations which are given by a composition of nabla integrals on an arbitrary time scale.

The Stieltjes string and its associated nodal points
Operators and Matrices, 2019 Based on the theory of Stieltjes strings first introduced by Gantmakher and Krein in [4], we define the nodal points for a Stieltjes string. We show that when the eigenvalue is maximal, there are exactly n+ 1 nodal points for the D-D problem and n nodal ...

Generalized Euler-Lagrange equations for variational problems with scale derivatives
, 2010 We obtain several Euler-Lagrange equations for variational functionals defined on a set of H\"older curves. The cases when the Lagrangian contains multiple scale derivatives, depends on a parameter, or contains higher-order scale derivatives are ...
