Fortuna, Elisabetta and Gianni, Patrizia and Luminati, Domenico (2005) Effective methods to compute the topology of real algebraic surfaces with isolated singularities. UNSPECIFIED. (Unpublished)
Given a real algebraic surface S in RP3, we propose a constructive procedure to determine the topology of S and to compute non-trivial topological invariants for the pair (RP3, S) under the hypothesis that the real singularities of S are isolated. In particular, starting from an implicit equation of the surface, we compute the number of connected components of S, their Euler characteristics and the weighted 2-adjacency graph of the surface.
