This result generalizes some works in nonlinear parabolic problems. Finally, in the last chapter, we study the existence and uniqueness of weak solution of initial boundary value problem for a super-linear parabolic equation with Neumann condition and integral condition of second type.enParabolic equationIntegral conditionSobolev spaceNonlinear parabolic equationOther
