On the Topological Classification of Real Enriques Surfaces. I
Viacheslav V. Nikulin
This note contains preliminary calculation of topological types or real Enriques surfaces. We realize 59 topological types of real Enriques surfaces (Theorem 6) and show that all o…
On the Brauer Group of Real Algebraic Surfaces
Viacheslav V. Nikulin
Let X be a real projective algebraic manifold, s numerates connected components of X(R) and _2Br(X) the subgroup of elements of order 2 of the cohomological Brauer group Br(X). We…
On Brauer Groups of Real Enriques Surfaces
V. V. Nikulin, R. Sujatha
Let Y be a real Enriques surface, _2Br(Y) the subgroup of elements of order 2 of Br(Y), and s, s_{or}, and s_{nor} the number of all connected, connected orientable, and connected…
On the Picard Number of Fano 3-Folds with Terminal Singularities
Viacheslav V. Nikulin
We prove the following main result: Let X be a Fano 3-fold with terminal Q-factorial singularities and X does not have a small extremal ray and a face of Kodaira dimension 1 or 2 f…
