“…The new techniques developed in this paper enabled him to prove a long sought after characterization of the rigid motion compatible Minkowski tensors in [2]. In recent years, tensor valuations were studied intensively (see, e.g., [3,5,18,21,22,25,28,46]). This is in part due to their applications in morphology and anisotropy analysis of cellular, granular or porous structures (see, e.g., [4,[41][42][43]).…”
