Inflection points and asymptotic lines on Lagrangean surfaces
J. Basto-Gonçalves
We describe the structure of the asymptotic lines near an inflection point of a Lagrangean surface, proving that in the generic situation it corresponds to two of the three possibl…

Local geometry of surfaces in
J. Basto-Gonçalves
The indicatrix or curvature ellipse and the characteristic curve of a surface in are presented, as well as the projective duality connecting them. The characterisatio…

The Gauss map for Lagrangean and isoclinic surfaces
Jose Basto-Gonçalves
Simple properties of the Gauss map characterise important classes of surfaces in $\Rq$: -surfaces, the real version of plane complex curves; Lagrangean surfaces; isoclinic surfa…
