Algebraic structures | Ring theory
In mathematics, a semifield is an algebraic structure with two binary operations, addition and multiplication, which is similar to a field, but with some axioms relaxed. (Wikipedia).

Mateusz Skomora: Separation theorems in signed tropical convexities
The max-plus semifield can be equipped with a natural notion of convexity called the โtropical convexityโ. This convexity has many similarities with the standard convexity over the nonnegative real numbers. In particular, it has been shown that tropical polyhedra are closely related to the
