Existence and Stability of Ulam–Hyers and Generalized Ulam–Hyers for the Generalized Langevin–Sturm–Liouville Equation Involving Generalized Liouville–Caputo Type

Journal of Mathematics
This paper focuses on investigating the existence, uniqueness, and stability of Ulam–Hyers (U-H) and generalized Ulam–Hyers (G-U-H) solutions for the generalized Langevin–Sturm–Liouville equation, which involves generalized Liouville–Caputo derivatives ...

Assessing the suitability of the Langevin equation for analyzing measured data through downsampling

Journal of Physics: Complexity
The measured time series from complex systems are renowned for their complex stochastic behavior, characterized by random fluctuations stemming from external influences and nonlinear interactions.

Stochastic cloaking: Concealing a region from diffusive particles

Physical Review Research
We introduce “stochastic cloaking,” where a region of space is concealed from an ensemble of diffusing particles whose individual trajectories are governed by a stochastic (Langevin) equation.

Combining the complex Langevin method and the generalized Lefschetz-thimble method

Journal of High Energy Physics, 2017
The complex Langevin method and the generalized Lefschetz-thimble method are two closely related approaches to the sign problem, which are both based on complexification of the original dynamical variables. The former can be viewed as a generalization of

Bottomonium continuous production from unequilibrium bottom quarks in ultrarelativistic heavy ion collisions

Physics Letters B, 2017
We employ the Langevin equation and Wigner function to describe the bottom quark dynamical evolutions and their formation into a bound state in the expanding Quark Gluon Plasma (QGP).

Existence Theory for a Class of Nonlinear Langevin Fractional (p,q)-Difference Equations in Banach Space

Mathematics
This paper is devoted to the study of existence results for a nonlinear Langevin-type fractional (p,q)-difference equation in Banach space. The considered model extends the fractional q-difference Langevin equation by introducing two parameters p and q ...
