WebAbstract. This paper is concerned with a simplified hydrodynamic equation, proposed by Ericksen and Leslie, modeling the flow of nematic liquid crystals. In dimension two, we establish both interior and boundary regularity theorems for such a flow under smallness conditions. As a consequence, we establish the existence of global (in time) weak ...

WebAug 31, 2024 · The smallest part of a crystal that has the three-dimensional pattern of the whole lattice is called a unit cell. This is the smallest repeating unit in the lattice. The edges of each unit cell ... WebA lattice is the symmetry group of discrete translational symmetry in n directions. A pattern with this lattice of translational symmetry cannot have more, but may have less symmetry than the lattice itself. [1] As a group (dropping its geometric structure) a lattice is a finitely-generated free abelian group, and thus isomorphic to .
WebCrystals are classified according to their symmetric prop- erties, i.e., we examine the isometries (distance- and angle-preserving mapping) of the three-dimensional Eu- clidian space that transform the crystal or crystal lattice (which is actually the same) into itself. In mathematics, crystals are Cartesian sections of certain fibered categories. They were introduced by Alexander Grothendieck (1966a), who named them crystals because in some sense they are "rigid" and "grow". In particular quasicoherent crystals over the crystalline site are analogous to quasicoherent modules over a scheme. An isocrystal is a crystal up to isogeny. They are $${\displaystyle p}$$-adic analogues of -adic étale
