Arithmetic and k-maximality of the cyclic free magma
(Algebra universalis, 2019)We survey free magmas and we explore the structure of their submagmas. By equipping the cyclic free magma with a second distributive operation we obtain a ringoid-like structure with some primitive ... -
Equidecomposable magmas
(Algebra universalis, 2020)A magma is called equidecomposable when the operation is injective, or, in other words, if x+y=x′+y′ implies that x=x′ and y=y′. A magma is free iff it is equidecomposable and graded, hence the notion ...
