We develop a new method for showing lower bounds for the time-space tradeof
f of polynomial evaluation procedures given by straight-line programs. By m
eans of this method we prove an asymptotically sharp lower bound for the ti
me-space tradeoff of general procedures of polynomial evaluation and exhibi
t specific families of univariate polynomials where this bound is reached.
