On CT and CSA Groups and Related Ideas

Benjamin Fine, Anthony Gaglione, Gerhard Rosenberger +1

A group is $G$ commutative transitive or CT if commuting is transitive on nontrivial elements. A group $G$ is CSA or conjugately separated abelian if maximal abelian subgroups are…

On the generalized Hurwitz equations and the Baragar-Umeda equations

Benjamin Fine, Gabriele Kern-Isberner, Anja I. S. Moldenhauer +1

We consider the generalized Hurwitz equation $a_{1} x_{1}^{2} + \dots + a_{n} x_{n}^{2} = d x_{1} \dots x_{n} - k$ and the Baragar-Umeda equation $a x^{2} + b y^{2} + c z^{2} = d x y z + e$ for solvability in integers.

Cryptographic protocols based on Nielsen transformations

Anja I. S. Moldenhauer, Gerhard Rosenberger

Based on a combinatorial distribution of shares we present in this paper secret sharing schemes and cryptosystems using Nielsen transformations.
