Abstract: Our aim in this paper is to study a modified higher-order (in space) phase field crystal model taking anisotropy into account. In particular, we deduce a priori estimates to prove well-posedness results and the dissipativity of the semigroup.

Keywords: Modified phase field crystal equation, higher-order models, anisotropy, a priori estimates, dissipative semigroup
