An application of the Sakai's theorem to the characterization of H*-algebras
The well-known Sakai's theorem, which states that every derivation acting on a von Neumann algebra is inner, is ,used to obtain a new elegant proof of the Saworotnow's characterization theorem for associative H*-algebras via two-sided H*-algebras.

Nil sets defined through generalized skew derivations having a Jordan-like behavior
Let R be a prime ring of characteristic different from [Formula: see text], C its extended centroid, F and G non-zero generalized skew derivations of R, associated with the same automorphism [Formula: see text] of R and [Formula: see text] a fixed ...

The Cyclically Resolvable Steiner Triple Systems of Order 57
A resolution of a Steiner triple system of order v (STS(v)) is point-cyclic if it has an automorphism permuting the points in one cycle. An STS(v) is cyclically resolvable if it has at least one point-cyclic resolution. Cyclically resolvable STS(v)s have

Almost automorphic derivative of an almost automorphic function
In this article are obtained conditions when the derivative of a continuous almost automorphic (an asymptotically almost automorphic, an almost periodic, an asymptotically almost periodic) function remains a continuous almost automorphic (an asymptotically almost automorphic, an almost periodic, an asymptotically almost periodic) function, respectively.

A Note on Fuzzy Automorphism and Inner Automorphism of Groups [PDF]
The fuzzification of classical set theory came into existence when Zadeh [1] laid down the concept of a fuzzy set as a generalization of a crisp set.

On (weakly) co-Hopfian automorphism-invariant modules
A module M over a ring R is called automorphism-invariant if M is invariant under automorphisms of its injective hull E(M) and M is called co-Hopfian if each injective endomorphism of M is an automorphism.

On topological groups of automorphisms
We study spaces X for which the space Homp(X) of automorphisms with the topology of point-wise convergence is a topological group. We identify large classes of spaces X for which Homp(X) is or is not a topological group.
