divided differences differential calculus jet functor scalar extension
2010/12/6
We define a simplicial differential calculus by generalizing divided differences from the case of curves to the case of general maps, defined on general topological vector spaces, or even on modules o...

Operational methods Lorentz-type equations of motion
2010/12/9
We propose an operational method for the solution of dierential equations involv-ing vector products. The technique we propose is based on the use of the evolution operator, dened in such a way that...

Recursive Generation of Isochronous Hamiltonian Systems
Isochronous Hamiltonian Systems collective coordinate $Q$ isochronous oscillators
2010/4/2
We propose a simple procedure to identify the collective coordinate $Q$ which is used to generate the isochronous Hamiltonian. The new isochronous Hamiltonian generates more and more isochronous oscil...

In this work an extended Jacobian elliptic function method is proposed and applied to the generalized shallow water wave equation. We systematically investigate to classify new exact travelling wave s...
Using pseudo-parabolic and fractional equations for option pricing in jump diffusion models
partial integro-differential equation jump diffusion models
2010/4/27
In mathematical finance a popular approach for pricing options under some Levy model is to consider underlying that follows a Poisson jump diffusion process. As it is well known this results in a part...
