On a space related to the affine building of type E7
Silvia Onofrei
A locally truncated geometry with diagram of type affine E7 is studied. One considers a parapolar space, locally of type A_{7,4}, which is subject to an extra axiom. A covering of…

A characterization of two classes of locally truncated diagram geometries
Silvia Onofrei
We study locally truncated geometries that are parapolar spaces locally of type A_{n-1,j}(K) with n>6 and j=3,4. Residually connected sheaves over these geometries are constructed.…
