The geometry of ranked symplectic matroids
Or Raz
This paper is a continuation of my paper "Lattices of flats for symplectic matroids". We explore geometric constructions originating from the lattice of flats of ranked symplectic…

Independent sets of non-geometric lattices and the maximal adjoint
Or Raz
We construct a family of independent sets for finite, atomic, and graded lattices, extending the well-known cryptomorphism between geometric lattices and matroids. This constructio…
