Abstract:
The Sarma-Eberlein estimate ${s_E}$ is an estimate of goodness of cubature formulae for n-cubes defined as the integral of the square of the formula truncation error, over a function space provided with a measure. In this paper, cubature formulae for the unit circle in ${{\mathbf {R}}^2}$ are considered and an estimate of the above type is constructed with the desirable property of being compatible with the symmetry group of the circle.References
