Error analysis of splitting methods for semilinear evolution equations [PDF]
, 2017 summary:We consider a Strang-type splitting method for an abstract semilinear evolution equation $$ \partial _t u = Au+F(u). $$ Roughly speaking, the splitting method is a time-discretization approximation based on the decomposition of the operators $A ...

Invariant measures as probabilistic tools in the analysis of nonlinear ODEs and PDEs
, 2023 We consider finite and infinite dimensional Hamiltonian systems and note that Gibbs measures are the unique probability measures satisfying an entropy and a classical Kubo–Martin–Schwinger (KMS) condition.

Mathematical Methods in the Applied Sciences, EarlyView.The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics
