摘要
We consider Chebyshev type quadrature formulas on an interval, i.e., quadrature formulas where all nodes are weighted equally. Using a topological method, we give an upper bound for the minimum number of nodes needed in order to achieve a certain degree of precision. We also consider the corresponding problem on the d-dimensional sphere Sd. © 1991.
