Infinite-Dimensional Lie Algebras of Generalized Block Type
This paper investigates a class of infinite-dimensional Lie algebras over a field of characteristic 0 which are called here Lie algebras of generalized Block type, and which generalize a class of Lie algebras originally defined by Richard Block. Under certain natural restrictions, this class of Lie algebras is shown to break into five subclasses. One of these subclasses contains all generalized Cartan type K Lie algebras and some Lie algebras of generalized Cartan type H, and a second one is the class of Lie algebras type L, which were previously defined and studied elsewhere by the authors. The other three types are hybrids of the first two types, and are new
Wetting on Lines and Lattices of Cylinders
This paper discusses wetting and capillary condensation transitions on a line
and a rectangular array of cylinders using an interface potential formalism.
For a line of cylinders, there is a capillary condensation transition followed
by complete wetting if the cylinders are sufficiently close together. Both
transitions disappear as the cylinder separation is increased. The dependence
of the wetting phase diagram of a rectangular array of cylinders is discussed
as a function of the chemical potential, substrate--fluid interaction strength
and surface tension.Comment: 17 pages in total: 11 pages of Latex document and 6 pages of figures,
