โœฆ Synopsis


A pre-natural class of modules over a ring R is one that is closed under isomorphic copies, submodules, arbitrary direct sums, and certain essential extensions. The set p r R of all pre-natural classes is a lattice, which contains many previously studied lattices of R-module classes. The sublattice structure of p r R is studied in this paper and is related to ring and module properties of R

In this paper, we introduce a new concept, namely, the J J, -irreducible monoid. Let G be a simple algebraic group. Let be a surjective endomorphism of G 0 0 ลฝ . such that G , the fixed points of G under , is finite. We construct a 0 0 ลฝ . J J, -irreducible monoid M with G the unit group. Extending
