Topological equivalence of complex polynomials
The following numerical control over the topological equivalence is proved:
two complex polynomials in variables and with isolated singularities
are topologically equivalent if one deforms into the other by a continuous
family of polynomial functions with
isolated singularities such that the degree, the number of vanishing cycles and
the number of atypical values are constant in the family.Comment: 14 pages, revised text for final versio

Precipitating antibodies in the carpet snake against parasitic nematodes
To our knowledge very little attention has been paid to the formation or presence of precipitating antibodies in the cold-blooded vertebrates. Indications of active antibody formation have nevertheless been reported in frogs, turtles and fish; however, these estimations were made using either agglutination or anaphylaxis. This communication is a survey of naturally occurring antibodies in the carpet snake (Morelia spilotes variegatus) which react positively with the body fluids of their nematode parasites, Amplicaecum robertsi, Ophidascarissp., and Polydelphissp., in interfacial precipitin ring tests
