Abstract
We discuss algebraic representations of mappings preserving arbitrary joins between submodule lattices For a given joinpreserving mapping bargmathfrakLleft RM rightto mathfrakLleft SN right between submodule lattices a representation is an Rbalanced mapping h B × M → N where S B R is a bimodule such that leftlangle hleft Btimes U right rightrangle =bargU for all Uin mathfrakLleft RM right We begin by posing the question in a general abstract context and by defining the canonical subrepresentation which is a representation if and only if there exists a representation The problem is to give easy and natural conditions for the existence of a representation We consider a very general situation for the mappings and give sufficient criteria for the existence of a representation We also consider lattice isomorphisms
