Minimal cubature formulas exact for Haar polynomials
The authors consider integration formulas which are exact for spaces of Haar polynomials in one or two variables. Among all cubature formulas, being exact for the same class of Haar polynomials, those with a minimal number of nodes are of special interest. In the present article the authors outline the research and construction of such cubature formulas.
