Abstract. In this work we investigate the pricing of swing options in a model where the underlying asset follows a jump diffusion process. We focus on the derivation of the partial integro-differential equation (PIDE) which will be applied to swing contracts and construct a novel pay-off function from a tree-based pay-off matrix that can be used as initial condition in the PIDE formulation. For valuing swing type derivatives we develop a theta implicit-explicit finite difference scheme to discretize the PIDE using a Gaussian quadrature method for the integral part. Based on known results for the classical theta-method the existence and uniqueness of solution to the new implicit-explicit finite difference method is proven. Various numerical examples illustrate the usability of the proposed method and allow us to analyse the sensitivity of swing options with respect to model parameters. In particular the effects of number of exercise rights, jump intensities and dividend yields will be investigated in depth.

Objectives: Evaluate the hemostasis and skin graft wound healing effect of autologous fibrin adhesive in experimental animals. Methods: experimental method, conducted on 6 rabbits to determine the role of fibrin glue in hemostasis, ability to heal skin graft in experimental rabbits through assessment of graft status: size, swelling, color, boundary between the puzzle piece and the surrounding skin. Results: 1/ Effective hemostasis: fibrin glue transplant: hemostasis time is 129.33±42.01 seconds, transplant time is 128.33±41.87 seconds; suture stitching: hemostasis time is 475.17±59.97 seconds, stitching time is 350.67±52.23 seconds. At times after 1 day, 3 days, 7 days, 10 days, 14 days, 20 days and 30 days there is an earlier phenomenon of wound healing, the flattened and scarred patch is more beautiful than the skin graft with sewing thread. Conclusions: Using autologous fibrin glue in skin grafting has the ability to stop bleeding, heal wounds and achieve better aesthetics than skin grafting with sutures.
