The Delta Invariant and Simultaneous Normalization for Families of Isolated Non-Normal Singularities
Gert-Martin Greuel, Gerhard Pfister
We consider families of schemes over arbitrary fields resp. analytic varieties with finitely many (not necessarily reduced) isolated non-normal singularities, in particular familie…

History of Singular and its relation to Zariski's multiplicty conjecture
Gert-Martin Greuel, Gerhard Pfister
We give a brief historical overview of the development of the Computer Algebra System SINGULAR: why it came about and how the development was related to the attempt to refute Zaris…

On Delta for parameterized Curve Singularities
Gert-Martin Greuel, Gerhard Pfister
We consider families of parameterizations of reduced curve singularities over a Noetherian base scheme and prove that the delta invariant is semicontinuous. In our setting, each cu…
