isomorphism class

isomorphism class

(mathematics)

A collection of all the objects isomorphic to a given object. Talking about the isomorphism class (of a poset, say) ensures that we will only consider its properties as a poset, and will not consider other incidental properties it happens to have.

The general procedure they present associates to every strongly local vertex operator algebra V a conformal net AV acting on the Hilbert space completion of V, and prove that the isomorphism class of AV does not depend on the choice of the scalar product on V.

We shall always identify a tree shape, an ordered tree shape, a cladogram, or an ordered cladogram, with its isomorphism class, and in particular we shall make henceforth the abuse of language of saying that two of these objects, T, T', are the same, in symbols T = T', when they are (only) isomorphic.

In Theorem 5.10 we show that for each isomorphism class D of skew diagrams, the number [r.sub.[lambda]] (D), of [lambda]-removable diagrams in D, can be expressed as a polynomial with rational coefficients in variables [r.sub.[lambda]] (C), where C runs over the set of all isomorphism classes of connected skew diagrams of size [absolute value of C] [less than or equal to] [absolute value of D].

Lemma 3.2 If exactly one representative of every isomorphism class of cubic connected graphs up to n - 2 vertices is given, then applying bundled triangle insertion to one member of each equivalence class of extensible sets that leads to a cubic connected graph on n vertices generates exactly one representative for every isomorphism class of cubic connected graphs on n vertices that contain reducible triangles.

By a classification we mean a cross-section for the isomorphism classes, i.e., a set of objects in which precisely one representative for each isomorphism class occurs.
