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 ...

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 ...

This is a preview. Log in through your library . Abstract If $L$ is a lattice, the automorphism group of $L$ is denoted $\mathrm{Aut}(L)$. It is known that given a ...

Algebraic varieties and their automorphism groups lie at the heart of modern algebraic geometry, intertwining deep theoretical concepts with practical applications. Algebraic varieties, defined as the ...

In the article Finitely presentable, non-Hopfian groups with Kazhdan's Property (T) and infinite outer automorphism group, Proc. Amer. Math. Soc. 135 (2007), 951—959, the second main result is the ...
