The Stochastic Balance Equation for the American Option Value Function and its Gradient [PDF]
arXiv, 2021 In the paper we consider the problem of valuation and hedging of American options written on dividend-paying assets whose price dynamics follow the multidimensional diffusion model. We derive a stochastic balance equation for the American option value function and its gradient.

Log-Conformation Representation of Hiperbolic Conservation Laws with Source Term
Trends in Computational and Applied Mathematics, 2014 The objective of this work is to study, through a simpler equation, the statement that the numerical instability associated to the high number of Weissenberg in equations with source term can be resolved by the use of the so called logarithmic ...

Kinetic equation consistent with the equation of state of nuclear matter [PDF]
, 1998 A kinetic equation which combines the quasiparticle drift of Landau's equation with a dissipation governed by a nonlocal and noninstant scattering integral in the spirit of Snider's equation for gases is derived.

A scalar hyperbolic equation with GR-type non-linearity
, 2003 We study a scalar hyperbolic partial differential equation with non-linear terms similar to those of the equations of general relativity. The equation has a number of non-trivial analytical solutions whose existence rely on a delicate balance between ...

New interpretation of the role of water balance in an extended Budyko hypothesis in arid regions [PDF]
Hydrology and Earth System Sciences, 2016 The Budyko hypothesis (BH) is an effective approach to investigating long-term water balance at large basin scale under steady state. The assumption of steady state prevents applications of the BH to basins, which is unclosed, or with significant ...
