Generalized variational principle for an accelerated pressureless gas model
Mack Dowell Komba Moudoumou, Fulgence Eyi Obiang, Octave Moutsinga
We examine a discrete model of sticky particles initially subjected to acceleration. We propose a novel generalized variational principle for characterizing clusters (i.e., particl…
A new class of stochastic processes with great potential for interesting applications
Fulgence Eyi Obiang, Paule Joyce Mbenangoya, Magloire Yorick Nguema MBA +1
This paper contributes to the study of a new and remarkable family of stochastic processes that we will term class . This class is potentially interesting because it unif…
Stochastic differential equations driven by relative martingales
Fulgence Eyi Obiang, Paule Joyce Mbenangoya, Ibrahima Faye +1
This paper contributes to the study of relative martingales. Specifically, for a closed random set , they are processes null on which decompose as , where is a cà…
Characterization of a new class of stochastic processes including all known extensions of the class
Fulgence Eyi Obiang, Paule Joyce Mbenangoye, Octave Moutsinga
This paper contributes to the study of class as well as the càdlàg semi-martingales of class , whose finite variational part is càdlàg instead of continuous. The two…
Backwards semi-martingales into Burgers' turtulence
Florent Nzissila, Octave Moutsinga, Fulgence Eyi Obiang
In fluid dynamics governed by the one dimensional inviscid Burgers equation , the stirring is explained by the sticky particles model. A Markov proce…
An ideal class to construct solutions for skew Brownian motion equations
Fulgence Eyi Obiang, Octave Moutsinga, Youssef Ouknine
This paper contributes to the study of stochastic processes of the class . First, we extend the notion of the above-mentioned class to càdlàg semi-martingales, whose finite va…
