    • Second Order Finite Volume IMEX Runge-Kutta Schemes for Two Dimensional Parabolic PDEs in Finance 

      López Salas, José Germán; Suárez Taboada, María; Castro Díaz, Manuel Jesús; Ferreiro Ferreiro, Ana María; García Rodríguez, José Antonio (Springer Nature, 2024-06-06)
      [Abstract]: We present a novel and general methodology for building second order finite volume implicit-explicit Runge-Kutta numerical schemes for solving two dimensional financial parabolic PDEs with mixed derivatives. ...
    • IMEX-RK Finite Volume Methods for Nonlinear 1d Parabolic PDEs. Application to Option Pricing 

      López Salas, José Germán; Suárez Taboada, María; Castro Díaz, Manuel Jesús; Ferreiro Ferreiro, Ana María; García Rodríguez, José Antonio (Springer Nature, 2024-06-06)
      [Abstract]: The goal of this paper is to develop 2nd order Implicit-Explicit Runge-Kutta (IMEX-RK) finite volume (FV) schemes for solving 1d parabolic PDEs for option pricing, with possible nonlinearities in the source and ...
    • High-order well-balanced numerical schemes for one-dimensional shallow-water systems with Coriolis terms 

      González Tabernero, Víctor; Castro, M.J.; García Rodríguez, José Antonio (Elsevier B.V., 2024-05-15)
      [Absctract]: The goal of this work is to develop high-order well-balanced schemes for the one-dimensional shallow-water equations with Coriolis terms. The main contribution is the development of general numerical methods ...
    • AMFR-W Numerical Methods for Solving High-Dimensional SABR/LIBOR PDE Models 

      López Salas, José Germán; Pérez-Rodríguez, Soledad; Vázquez, Carlos (Society for Industrial and Applied Mathematics (SIAM), 2021-01)
      [Abstract]: In this work, we mainly develop a new numerical methodology to solve a PDE model recently proposed in the literature for pricing interest rate derivatives. More precisely, we use high-order-in-time AMFR-W-methods, ...
    • Global optimization for data assimilation in landslide tsunami models 

      Ferreiro Ferreiro, Ana María; García Rodríguez, José Antonio; López Salas, José Germán; Escalante Sánchez, Cipriano; Castro Díaz, Manuel Jesús (Elsevier, 2020-02-15)
      [Abstract]: The goal of this article is to make automatic data assimilation for a landslide tsunami model, given by the coupling between a non-hydrostatic multi-layer shallow-water and a Savage-Hutter granular landslide ...
