Time-dependent non-homogeneous stochastic epidemic model of SIR type
Autor: Mireia Besalú, Giulia Binotto
Publikováno v: AIMS Mathematics, Vol 8, Iss 10, Pp 23218-23246 (2023)
To better describe the spread of a disease, we extend a discrete time stochastic SIR-type epidemic model of Tuckwell and Williams. We assume the dependence on time of the number of daily encounters and include a parameter to represent a possible quar

Direct-coupling analysis (DCA) for studying the coevolution of residues in proteins has been widely used to predict the three-dimensional structure of a protein from its sequence. We present RADI/raDIMod, a variation of the original DCA algorithm tha

Existence and smoothness of the density of the solution to fractional stochastic integral Volterra equations
Autor: David Márquez-Carreras, Mireia Besalú, Eulalia Nualart
Publikováno v: Dipòsit Digital de la UB
Universidad de Barcelona
We consider stochastic Volterra integral equations driven by a fractional Brownian motion with Hurst parameter H>12. We first derive supremum norm estimates for the solution and its Malliavin derivative. We then show existence and smoothness of the d

Delay Equations with Non-negativity Constraints Driven by a Hölder Continuous Function of Order $\beta \in \left(\frac13,\frac12\right)$
Autor: Carles Rovira, David Márquez-Carreras, Mireia Besalú
Publikováno v: Potential Analysis. 41:117-141
In this note we prove an existence and uniqueness result of solution for multidimensional delay differential equations with normal reflection and driven by a Holder continuous function of order \(\beta \in (\frac13,\frac12)\). We also obtain a bound

ESTIMATES FOR THE SOLUTION TO STOCHASTIC DIFFERENTIAL EQUATIONS DRIVEN BY A FRACTIONAL BROWNIAN MOTION WITH HURST PARAMETER H ∈ (⅓, ½)
Autor: David Nualart, Mireia Besalú
Publikováno v: Stochastics and Dynamics. 11:243-263
In this paper we establish precise estimates for the supremum norm for the solution of a dynamical system driven by a Hölder continuous function of order between ⅓ and ½ using the techniques of fractional calculus. As an application we deduce the

Gaussian-type lower bounds for the density of solutions of SDEs driven by fractional Brownian motions
Autor: Samy Tindel, Arturo Kohatsu-Higa, Mireia Besalú
Publikováno v: Ann. Probab. 44, no. 1 (2016), 399-443
In this paper we obtain Gaussian-type lower bounds for the density of solutions to stochastic differential equations (SDEs) driven by a fractional Brownian motion with Hurst parameter $H$. In the one-dimensional case with additive noise, our study en
