Automorphism groups of minimal real-analytic CR manifolds
, 2013 We show that the local automorphism group of a minimal real-analytic CR manifold M is a finite dimensional Lie group if (and only if) M is holomorphically nondegenerate by constructing a jet parametrization.

Cosine and Sine Addition and Subtraction Law with an Automorphism
Annales Mathematicae SilesianaeLet S be a semigroup. Our main results are that we describe the complex-valued solutions of the following functional equations g(xσ(y))=g(x)g(y)+f(x)f(y),x,y∈S,f(xσ(y))=f(x)g(y)+f(y)g(x),x,y∈S,\matrix{ {g\left( {x\sigma \left( y \right)} \right) = g ...

An application of the Sakai's theorem to the characterization of H*-algebras
International Journal of Mathematics and Mathematical Sciences, 1995 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.

The Moduli Space of Principal G2-Bundles and Automorphisms
MathematicsLet X be a compact Riemann surface of genus g≥2 and M(G2) be the moduli space of polystable principal bundles over X, the structure group of which is the simple complex Lie group of exceptional type G2.

K3 surfaces with a non-symplectic automorphism and product-quotient surfaces with cyclic groups
, 2013 We classify all the K3 surfaces which are minimal models of the quotient of the product of two curves $C_1\times C_2$ by the diagonal action of either the group $\Z/p\Z$ or the group $\Z/2p\Z$.
