Linear and nonlinear pseudo-differential operators on p-adic fields

Recently, wavelet analysis over the p-adic fields are widely used in physics, biology and geophysics. In this paper, p-adic wavelets are used to study various p-adic pseudo-differential equations. p-Adic analogue of wave equation and general linear second order pseudo-differential equation are solved using both Haar and non-Haar wavelets. Finally, the existence of solutions of nonlinear p-adic pseudo differential equation and p-adic analogue of Navier Stokes equation are proved using the Schauder fixed point theorem together with wavelet functions.
