classes of algebras (Topic)

Classes of algebras are of two types: either classes of specific algebras, such as: group algebras, K-algebras, groupoid algebras, logic algebras, and so on, or general ones, such as general classes of: categorical algebras, higher dimensional algebra (HDA), supercategorical algebras, universal algebras, and so on.

Definition 0.1   A class of algebras is defined in a precise sense as an algebraic object in the groupoid category.

Remarks With the above definition, one can also define a category of classes of algebras and their associated groupoid homomorphisms which is then an algebraic category.

Although all classes can be regarded as equivalence, weak equivalence, etc., classes of algebras (either specific or general ones), do not define identical, or even isomorphic structures, as the notion of `equivalence' can have more than one meaning even in the algebraic case.

class $ algebras$??? by PrimeFan on 2008-07-23 19:51:34
What exactly is the point of setting off that word in that manner sometimes and sometimes not?
