Estimates of Periods and Global Continua of Periodic Solutions for State-Dependent Delay Equations

open access: yesSIAM Journal on Mathematical Analysis, 2012
Consider the state-dependent delay differential equation (SDDDE) \[ x'(t) = f(x(t), x(t-\tau(t)), \sigma),\quad \tau'(t) = g(x(t), \tau(t), \sigma), \] where \(x(t) \in {\mathbb R}^N\), \(0 \leq \tau(t)

The structure of Rabinowitz' global bifurcating continua for problems with weak nonlinearities

open access: yesMathematika, 1997
Summary: Rabinowitz' global bifurcation theorem shows that for a large class of nonlinear eigenvalue problems a continuum (i.e., a closed, connected set) of solutions bifurcates from the trivial solution at each eigenvalue (or characteristic value) of odd multiplicity of the linearized problem (linearized at the trivial solution).

Bifurcation from zero or infinity in nonlinearizable Sturm–Liouville problems with indefinite weight

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
In this paper, we consider bifurcation from zero or infinity of nontrivial solutions of the nonlinear Sturm–Liouville problem with indefinite weight. This problem is mainly important because of it is related with a selection-migration model in genetic ...

The Importance of Measuring Mental Wellbeing in the Context of Psychological Distress: Using a Theoretical Framework to Test the Dual-Continua Model of Mental Health

open access: yesBehavioral Sciences, 2023
The dual-continua model of mental health suggests that psychological distress and mental wellbeing operate on two distinct yet related continua, both uniquely contributing to overall mental health.
