TY - JOUR AU - Cheung, Wing-Sum AU - Zhao, Chang-Jian PY - 2007 DA - 2007/05/13 TI - On Opial-Type Integral Inequalities JO - Journal of Inequalities and Applications SP - 038347 VL - 2007 IS - 1 AB - We establish some new Opial-type inequalities involving functions of two and many independent variables. Our results in special cases yield some of the recent results on Opial's inequality and also provide new estimates on inequalities of this type.
