Abstract:
The author obtains a classification, to within a rigid isotopy (i.e. an isotopy in the class of algebraic surfaces), of algebraic surfaces of degree four in $\mathbf Cp^3$ with isolated singularities which have at least one nonsimple singular point (i.e. a singular point different from $A_p$, $D_p$, $E_6$, $E_7$, and $E_8$).
