Split buildings of type F4 in buildings of type E6
Anneleen De Schepper, N. S. Narasimha Sastry, Hendrik Van Maldeghem
A symplectic polarity of a building Δ of type E6 is a polarity whose fixed point structure is a building of type F4 containing residues isomorphic to symplectic polar spaces (i.e.,…

Maps related to polar spaces preserving a Weyl distance or an incidence condition
A. De Schepper, H. Van Maldeghem
Let and be the sets of elements of respective types and of a polar space~ of rank at least , viewed as a Tits-building. For any Weyl distance between…
