Title:  Computing without subtracting (and/or dividing)

Abstract:  Algebraic complexity of a rational function can be defined as the minimal number of arithmetic operations required to compute it. Suppose that some of the four basic operations (say, subtraction and/or division) have been disallowed---can this restriction dramatically change the complexity of a given function? Some questions of this nature are relatively easy to answer, some are not. The talk is based on joint work with D. Grigoriev (Bonn) and G. Koshevoy (Moscow).
