  The glider Brauer-Severy variety GBS(A) of a central simple algebra A over a
field K is introduced as the set of all irreducible left glider ideals in A for
some filtration FA. For fields we deduce that GBS(K) equals R(K) x Z, the
product of the Riemann surface of K and the ring of integers Z. For a csa A
over K it turns out that GBS(A) = BS(A) x GBS(K), where BS(A) denotes the
classical Brauer-Severi variety of A.
