Informally, a dynamic system is any physical system that evolves with time (e.g., a pendulum, a planet orbiting the sun, the weather, etc). From a more mathematically precise perspective, one can ...

From the late 1970s to the early 1980s, Köhler developed a theory for constructing finite quadruple systems with point-transitive Dihedral automorphism groups by introducing a certain algebraic graph, ...

Automorphism-invariant modules have emerged as a linchpin in the study of modern algebra, especially in the context of module theory over noncommutative rings. These modules are defined by the ...

Coxeter theory investigates groups generated by reflections and the geometric structures arising from their actions, such as root systems and Dynkin diagrams. This body of work underpins vast areas of ...

The Journal of Operator Theory endeavours to publish significant articles in all areas of operator theory, operator algebras and closely related domains. All accepted manuscripts are carefully ...

In many typical situations, the countable universal homogeneous model of some first-order theory has the property that its automorphism group contains a homeomorphic copy of the automorphism group of ...
