PL 4-manifolds admitting simple crystallizations: framed links and regular genus
M. R. Casali, P. Cristofori, C. Gagliardi
Simple crystallizations are edge-coloured graphs representing PL 4-manifolds with the property that the 1-skeleton of the associated triangulation equals the 1-skeleton of a 4-simp…

Cataloguing PL 4-manifolds by gem-complexity
M. R. Casali, P. Cristofori
We describe an algorithm to subdivide automatically a given set of PL n-manifolds (via coloured triangulations or, equivalently, via crystallizations) into classes whose elements a…

The double of the doubles of Klein surfaces
Antonio F. Costa, Paola Cristofori, Ana M. Porto
A Klein surface is a surface with a dianalytic structure. A double of a Klein surface is a Klein surface such that there is a degree two morphism (of Klein surfaces) $Y\rig…
