Nonlinear boundary value problems and operators TT∗
Journal of Differential Equations, 1978 AbstractWe consider nonlinear boundary value problems of the type Lƒ + Nƒ = 0 for the existence of solutions. It is assumed that L is a 2nth-order linear differential operator in the real Hilbert space S = L2[a, b] which admits a decomposition of the form L = TT∗ where T is an nth-order linear differential operator and N is a nonlinear operator defined

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Solvability of a three-point nonlinear boundary-value problem
Electronic Journal of Differential Equations, 2010 Using the Leray Schauder nonlinear alternative, we prove the existence of a nontrivial solution for the three-point boundary-value problem $$displaylines{ u''+f(t,u)= 0,quad 0<t<1 cr u(0)= alpha u'(0),quad u(1)=eta u'(eta ), }$$ where $eta ...

Nonlinear boundary value problems in Hilbert Spaces
Journal of Mathematical Analysis and Applications, 1989 The authors consider the nonlinear two point boundary value problem (*) \(y''=f(t,y,y')\), \(0\leq t\leq 1\), with Sturm-Liouville type boundary conditions. A solution of (*) is a twice continuously differentiable function which takes values in a real Hilbert space H.
