Polynomial interpolation to analytic functions can be very accurate, depending on the distribution of the interpolation nodes. However, in equispaced nodes and the like, besides being badly ...

Let Rm n (C) be the complex rational functions defined on \lbrack 0,1\rbrack with numerators and denominators having degrees not exceeding m and n respectively. We determine properties of the best ...

The statistical physics of graphs and partition functions represents a vibrant intersection of graph theory, statistical mechanics and computational complexity. By summing over an ensemble of ...
