Mateusz Skomora: Separation theorems in signed tropical convexities

The max-plus semifield can be equipped with a natural notion of convexity called the โ€œtropical 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
