The group isomorphy, however, is not to be expected: Since the base centralizer B(A) and the holonomy centralizer Z (HA ) are isomorphic groups, it is unlikely that there arise isomorphic groups from originally non-isomorphic groups by factorization.
On the Gribov Problem for Generalized Connections
First we address the question of isomorphy and anti-isomorphy of these semirings.
Classification of finite congruence-simple semirings with zero
Table 1 shows the smallest nontrivial idempotent commutative monoids M (up to isomorphy), represented by the Hasse-diagram of the corresponding lattices, together with the semirings in the collection SR(M ).
Classification of finite congruence-simple semirings with zero
Kostrikin and Kuznetsov described the orbits under the action of the group O(5) of automorphisms of o(5) (see [FG]) in the variety of Lie algebras containing L(−1) ≃ o(5), which means that Kostrikin and Kuznetsov listed all isomorphy classes of the members of the 5-parameter family of deforms of o(5).
Deformations of the Lie algebra o(5) in characteristics 3 and 2
Study their integrability, isomorphy classes of the deforms, and their interpretations as in (b).

C → S and Pf are as before and φ is an isomorphis of local system of Fl vector spaces compatible with the symplectic structure.
Degeneration of curves and analytic deformation
Actually there exist two different isomorphy classes of such small resolutions.
Some Siegel threefolds with a Calabi-Yau model II
This divisor is well-deﬁned up to the choice of the isomorphi sm Lη → OX ,η or, equivalently, up to the choice of a principal divisor, which is an Arakelov divisor D = (cid:229) n p · p of norm N (D) = (cid:213) n p = 1 (since the class number of Q is 1).
Blueprints - towards absolute arithmetic?
Let ˆG denote the unitary dual of G, i.e., it is the set of all isomorphy classes of irreducible unitary representations of G.
A conjectural Lefschetz formula for locally symmetric spaces
Such a dual antilinear isomorphism is the origin of Dirac’s bra-ket notation V ∗↔ V T , ej = |ej i ↔ hej | = dj k ˇek , dj k = hej |ek i With the scalar product induced isomorphy there is an antilinear isomorphy ∼= also for the tensor representation of the endomorphisms, e.g.
The Hilbert spaces for stable and unstable particles
We use Theorem 1.1 to show that the symplectic strange duality formulated by Beauville [B] is, in a suitable sense, projectively ﬂat: Hence it is an isomorphi sm for all curves of a given genus if it is an isomorphism for some curve of that genus (see Corollary 5.1).
Orthogonal bundles, theta characteristics and the symplectic strange duality
As an application of the general investigation sketched above, we obtain in Sections 9 and 10 applications to weak anabelian geometry where the fundamental group shall determine the isomorphy type of a curve.
On cuspidal sections of algebraic fundamental groups
The pointed set of isomorphy classes of Γ-equivariant right N -torsor will be denote by TorsΓ (N ) with P = N and right translation as the special element.
On cuspidal sections of algebraic fundamental groups
The isomorphy class of the twist does not depend on the choice.
On cuspidal sections of algebraic fundamental groups
We also often do not distinguish between a representation and its isomorphy class and write “equal” for “isomorphic”.
