-tensor gradient flow with quasi-entropy and discretizations preserving physical constraints
Yanli Wang, Jie Xu
We propose and analyze numerical schemes for the gradient flow of -tensor with the quasi-entropy. The quasi-entropy is a strictly convex, rotationally invariant elementary funct…

Classifying local anisotropy formed by rigid molecules: symmetries and tensors
Jie Xu
We consider an infinitesimal volume where there are many rigid molecules of the same kind, and discuss the description and classification of the local anisotropy in this volume by…
