A geometric realization of socle-projective categories for posets of type $\mathbb{D}$

Gabriel Bravo Rios, Ralf Schiffler, Robinson-Julian Serna

We introduce posets of type $\mathbb{D}$, a family of posets described by an admissible Dynkin quiver of type $D_n$ together with a compatible set of extra arrows (alien arrows), a…
