Homoclinic solutions in periodic partial difference equations

Advances in Nonlinear Analysis
By using critical point theory in combination with periodic approximations, we obtain novel sufficient conditions for the existence of nontrivial homoclinic solutions for a class of periodic partial difference equations with sign-changing mixed ...

Hybrid Modeling and Optimization of Yogurt Starter Culture Continuous Fermentation [PDF]

Bioautomation, 2009
The present paper presents a hybrid model of yogurt starter mixed culture fermentation. The main nonlinearities within a classical structure of continuous process model are replaced by neural networks.

Normalized Ground States for Mixed Fractional Schrödinger Equations with Combined Local and Nonlocal Nonlinearities

Fractal and Fractional
This paper studies the existence, regularity, and properties of normalized ground state solutions for the mixed fractional Schrödinger equations. For subcritical cases, we establish the boundedness and Sobolev regularity of solutions, derive Pohozaev ...

Subcritical nonlocal problems with mixed boundary conditions

Bulletin of Mathematical Sciences
By using linking and [Formula: see text]-theorems in this paper we prove the existence of multiple solutions for the following nonlocal problem with mixed Dirichlet–Neumann boundary data, (−Δ)su = λu + f(x,u)in Ω,u = 0 on Σ𝒟,∂u ∂ν = 0 on Σ𝒩, where ...

Calculation of mixing in nonlinear circuits

Electronics Letters, 1985
A novel scheme is described for calculating the harmonic response of a nonlinear circuit driven by two or more signals incommensurate in frequency. The method, which is a natural extension of the harmonic balance technique, is not limited by the degree of nonlinearity or signal strengths nor by their proximity in frequency.

Kramers dichroism in PT-symmetric magnets

Physical Review Research
The quantum states in doubly degenerate Kramers pairs can act as an internal degree of freedom. Here, we uncover a Kramers dichroism in PT-symmetric magnets: interband transitions induced by circularly polarized light irradiation can selectively polarize
