. The term "module" is often used synonymously for a representation; for the module-theoretic terminology, see also
glossary of module theory Module theory is the branch of mathematics in which module (mathematics), modules are studied. This is a glossary of some terms of the subject. See also: ''Glossary of linear algebra'', ''Glossary of ring theory'', ''Glossary of representation the ...
. See also Glossary of Lie groups and Lie algebras, list of representation theory topics and :Representation theory. Notations: We write \mathbb_m = GL_1. Thus, for example, a one-representation (i.e., a character) of a group ''G'' is of the form \chi: G \to \mathbb_m.
