2. Mathematics A one-to-one correspondence between the elements of two sets such that the result of an operation on elements of one set corresponds to the result of the analogous operation on their images in the other set.
3. A close similarity in the crystalline structure of two or more substances of similar chemical composition.

(For irregular cusps, this is square root of local coordinate.) When m = 1, this is the Shioda isomorphism [mathematical expression not reproducible].
Institutional isomorphism is determined by the interplay between three discrete modes of isomorphism: normative, coercive, and mimetic isomorphism (DiMaggio & Powell, 1983).
Because f is a group isomorphism, we get [phi] is well defined.
In this study, we examine the effects of five CPA strategies on subsidiary legitimacy, namely, financial incentive, information, constituency building, mimetic isomorphism and relational.
The pressures to maintain internal isomorphism are mitigated in emerging economies since it is critical for the firm to maintain external isomorphism to survive and to grow in such environments (Francis et al., 2009).
On the other hand, we introduce the operator [mathematical expression not reproducible], onto [L.sub.2](R), and its restriction to [F.sup.2.sub.(n)] (C) is an isometric isomorphism. Thus, the adjoint operator [R.sup.*.sub.(n)] = [U.sup.*] [R.sub.0,(n)] is an isometric isomorphism from [L.sub.2](R) onto the subspace [F.sup.2.sub.(n)]) (C).
Monomorphism is the inexact-matching which gets rid of the bidirectional requirement of edge-remaining bases on subgraph isomorphism. It requires that every node of the first graph can map different nodes and edges in the second graph, which allows the redundant edges and nodes.
Scholars' thoughts diverged referring to motivations of isomorphism. Babones (2013) mentioned that isomorphism takes place either through emulation (a macro- phenomenological mechanism) or through coercion (a macro-realist mechanism).
Mizruchi and Fein (1999) suggest that pressure from external resource providers results in coercive isomorphism and "is thus analogous to formulations of the resource dependency model in which organizations are viewed as constrained by those on whom they depend for resources" (p.
'The Iron Cage Revisited: Collective Rationality and Institutional Isomorphism in Organizational Fields'.
In the case of string links f and g we show also that if we have a braid-special isomorphism between the n-level group diagrams for f and g, then there is a certain relation between f and g that depends on the kernel of the "Artin representation" (Theorem 6).
If i < n, then [mathematical expression not reproducible] and therefore [mathematical expression not reproducible] and from the isomorphism [mathematical expression not reproducible] for all i, one can suppose that [mathematical expression not reproducible] Therefore, there exists an element x [member of] [m.sub.0] such that it is an M-sequence.
