This man names a type of filter with a steeper roll-off rate than a Butterworth filter.
The roots of this man's namesake polynomial are useful for interpolation as they minimize the oscillation around the interval edges known as Runge's phenomenon. Those polynomials are also used in the Clenshaw-Curtis quadrature for numerical integration. The observation that there are more 3 modulo 4 prime numbers than 1 modulo 4 is a "bias" named for this man. This man names a type of filter with a steeper roll-off rate than a Butterworth filter. The probability of data being within k times sigma of the mean is less than one over k squared according to this man. That statement can be proven by using Markov's inequality. For 10 points, name this Russian mathematician whose namesake inequality gives an upper bound on the number of data points at some distance from the mean.
