Predictability and uniqueness of weak solutions of the stochastic differential equations

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
Causality is a topic which receives much attention nowadays and it represents a prediction property in the context of possible reduction of available information in order to predict a given filtration.

The geometry of the space of branched rough paths

open access: yesProceedings of the London Mathematical Society, Volume 121, Issue 2, Page 220-251, August 2020., 2020
Abstract We construct an explicit transitive free action of a Banach space of Hölder functions on the space of branched rough paths, which yields in particular a bijection between these two spaces. This endows the space of branched rough paths with the structure of a principal homogeneous space over a Banach space and allows to characterize its ...

The influence of the noise on the exact solutions of a Kuramoto-Sivashinsky equation

open access: yesOpen Mathematics, 2022
In this article, we take into account the stochastic Kuramoto-Sivashinsky equation forced by multiplicative noise in the Itô sense. To obtain the exact stochastic solutions of the stochastic Kuramoto-Sivashinsky equation, we apply the G′G\frac{{G ...

Quasi‐shuffle algebras and renormalisation of rough differential equations

open access: yesBulletin of the London Mathematical Society, Volume 52, Issue 1, Page 43-63, February 2020., 2020
Abstract The objective of this work is to compare several approaches to the process of renormalisation in the context of rough differential equations using the substitution bialgebra on rooted trees known from backward error analysis of B‐series. For this purpose, we present a so‐called arborification of the Hoffman–Ihara theory of quasi‐shuffle ...

Existence and uniqueness of solutions for the stochastic Volterra-Levin equation with variable delays

open access: yesOpen Mathematics, 2022
The Picard iteration method is used to study the existence and uniqueness of solutions for the stochastic Volterra-Levin equation with variable delays. Several sufficient conditions are specified to ensure that the equation has a unique solution.

Uniqueness of stable processes with drift [PDF]

open access: yes, 2013
Suppose that d ≥ 1 and α ∈ (1, 2). Let Y be a rotationally symmetric α-stable process on R d and b a R-valued measurable function on R belonging to a certain Kato class of Y .

Impacts of Brownian motion and fractional derivative on the solutions of the stochastic fractional Davey-Stewartson equations

open access: yesDemonstratio Mathematica, 2023
In this article, the stochastic fractional Davey-Stewartson equations (SFDSEs) that result from multiplicative Brownian motion in the Stratonovich sense are discussed.

Influence of section depth on the structural behaviour of reinforced concrete continuous deep beams [PDF]

open access: yes, 2007
YesAlthough the depth of reinforced concrete deep beams is much higher than that of slender beams, extensive existing tests on deep beams have focused on simply supported beams with a scaled depth below 600 mm.

On the stability of solutions to conformable stochastic differential equations

open access: yes, 2020
In this paper, we study the stability of solutions to conformable stochastic differential equations. Firstly, we show the trivial solution are stochastially stable, stochastically asymptotically stable and almost surely exponentially stable, respectively.

Existence and Comparisons for BSDEs in general spaces [PDF]

open access: yes, 2010
We present a theory of Backward Stochastic Differential Equations in continuous time with an arbitrary filtered probability space. No assumptions are made regarding the continuity of the filtration, or of the predictable quadratic variations of ...
