Almost periodic solutions of anisotropic elliptic-parabolic equations with variable exponents of nonlinearity

Mykola Bokalo

Abstract:
We prove the well-posedness of Fourier problems for anisotropic elliptic-parabolic equations with variable exponents of nonlinearity without any restrictions at infinity. We obtain estimates of the weak solutions and conditions for the existence of periodic and almost periodic solutions. In addition, some properties of the weak solutions of the Fourier problem are considered.
