In this paper,some existence results for the fourth order nonlinear subelliptic equations on the Hesisenberg group are given by means of varational methods.
Under the hypotheses that the second-order and third-order derivatives of a function are bounded, an estimate of the radius of the convergence ball of Ostrowski
The pressureless Navier-Stokes equations for non-Newtonian fluid are studied.The analytical solutions with arbitrary time blowup,in radial symmetry,are construc
Stationary even single-bump periodic solutions of the Swift-Hohenberg equation are analyzed. The coefficient kin the equation is found to be a critical paramete
