Resumen de A quasi-trapezoid inequality for double integrals

Sever Silvestru Dragomir, Charles E.M. Pearce, N.S. Barnett

• A quasi-trapezoid inequality is derived for double integrals that strengthens considerably existing results. A consonant version of the Grüss inequality is also derived. Applications are made to cubature formulae and the error variance of a stationary variogram.
