We consider the convergence of Gauss-type quadrature formulas for the integral R1 0 f(x)!(x)dx ,w here! is a weight function on the half line (0;1). The n-point Gauss-type quadrature formulas are constructed such that they are exact in the set of Laurent polynomials p;q 1 =f Pq 1 k= pakx kg, where p = p(n) is a sequence of integers satisfying 0 p(n) 2n and q = q(n )=2 n p(n). It is proved that under certain Carleman-type conditions for the weight and when p(n )o rq(n )g oes to1, then convergence holds for all functions f for which f! is integrable on (0;1). Some numerical experiments compare the convergence of these quadrature formulas with the convergence of the classical Gauss quadrature formulas for the half line. |
