Theoretical analysis of numerical integration rule for nonlinear goursat problem
, 2016 Many nonlinear problems that arise in various science and engineering fields can be modelled by the Goursat partial differential equations. Modelling these non-linear problems using the Goursat partial differential equations has not received much ...

A non-linear Goursat problem for a high order polyvibrating equation
, 1986 SynopsisThis paper proves the existence of a solution of a non-linear Goursat problem for a partial differential equation of order 2p (p ≧ 2) with the boundary conditions given on 2p curves emanating from a common point.
