Published in 2019 at "Afrika Matematika"

DOI: 10.1007/s13370-019-00677-0

Abstract: The aim of this paper is to give the predictable representation property associated with Lévy process in the non-homogeneous case. In this latter, we establish the existence and uniqueness of solution for the Backward Stochastic… read more here.

Published in 2021 at "Journal of Mathematical Physics"

DOI: 10.1063/5.0038740

Abstract: This paper studies time-inhomogeneous diffusion processes, including both Brownian dynamics and Langevin dynamics. We derive upper bounds of the relative entropy production for a time-inhomogeneous process with respect to the transient invariant probability measures. We… read more here.

Published in 2018 at "Journal of Statistical Mechanics: Theory and Experiment"

DOI: 10.1088/1742-5468/aae028

Abstract: We consider Markov chains with random transition probabilities which, moreover, fluctuate randomly with time. We describe such a system by a product of stochastic matrices, $U(t)=M_t\cdots M_1$, with the factors $M_i$ drawn independently from an… read more here.

Published in 2019 at "Physical review letters"

DOI: 10.1103/physrevlett.123.130602

Abstract: We provide a new hydrodynamic framework to describe out-of-equilibrium integrable systems with space-time inhomogeneous interactions. Our result builds up on the recently introduced generalized hydrodynamics (GHD). The method allows us to analytically describe the dynamics… read more here.

Published in 2022 at "IEEE Access"

DOI: 10.1109/access.2022.3199425

Abstract: Detecting financial fraud to profile crimes and pinpoint system vulnerabilities is an essential issue in the financial industry. Because of interpretability requirements and the lack of mass transaction data due to privacy regulations, sophisticated handcrafted… read more here.
