Abstract
In this paper we demonstrate the existence, uniqueness and continuous dependence of a strong solution upon the data, for a mixed problem which
combine classical boundary conditions and an integral condition, such as
the total mass, flux or energy, for a third order parabolic equation. We
present a functional analysis method based on an a priori estimate and on
the density of the range of the operator generated by the studied problem.
