The invariance of the $n$-th semivariational approximation with respect to the polynomial bases and its coincidence with the $n$-th Padé approximation at the basic time instants are proved for the case of the homogeneous abstract parabolic equation. The method and theorems are also extended to parabolic problems with inhomogeneous boundary conditions and to equations with two positive definite operators.
