Abstract
In this paper, we present proofs of the regularity criterion for weak solutions to a generalized liquid crystal model with fractional diffusion and thermal effects. Specifically, we prove that if certain decay estimates hold, the solutions \((u, d, \theta )\), representing the velocity field, the orientation vector in the crystal and the temperature field respectively, are regular at the origin. We employ the extension technique for the fractional Laplacian and establish decay estimates to demonstrate the boundedness and regularity of the solutions. Our results aim to extend classical theories by introducing anomalous dissipation and thermal influences, leading to potentially increase the framework for the analysis of liquid crystal models under varying conditions.
期刊介绍:
The Brazilian Journal of Physics is a peer-reviewed international journal published by the Brazilian Physical Society (SBF). The journal publishes new and original research results from all areas of physics, obtained in Brazil and from anywhere else in the world. Contents include theoretical, practical and experimental papers as well as high-quality review papers. Submissions should follow the generally accepted structure for journal articles with basic elements: title, abstract, introduction, results, conclusions, and references.
