Geometric Radicals of Polynomial Ideals
by Eberhard Becker
The talk is concerned with various notions of radicals of a polynomial
ideals, e.g. the usual radical as in commutative algebra or the real
radical in case the ground field is real itself. In great generality,
this is a topic addressed by V. Weispfenning in an earlier paper.
After discussing the concept of a "radical operation" we will concentrate
on binomial ideals where several detailed results can be obtained
even for more general types of radicals fitting in the concept of
radical operations.
Volker Weispfenning: Scientist, Teacher, Mentor
by Thomas Becker
This talk is an attempt by a former student and apprentice to pay
homage to Volker Weispfenning's work as a mathematical researcher,
teacher, and mentor. The author describes his perception of Volker
Weispfenning's mathematical achievements, and he gives a personal
account of the way in which Volker Weispfenning's teaching and
mentoring has impacted his life and career.
REDUCE: The First Forty Years
by Anthony Hearn
Volker Weispfenning and his group in Passau have had a long interest
in computer algebra. In this talk, REDUCE, one of the algebra programs
they use, will be discussed. The development of this program began
over forty years ago. We shall discuss the design decisions that have
influenced its longterm survival, and the way in which the program
has evolved with time.
