Abstract: We expand the quartic variations in time and the quadratic variations in space of the solution to a stochastic partial differential equation with piecewise constant coefficients. Both expansions allow us to deduce an estimation method of the parameters appearing in the equation.
Keywords: Quartic and quadratic variations, stochastic partial differential equations, discontinuity, integration techniques, special functions, estimation of parameters.
