%0 Journal Article %T On Opial-Type Integral Inequalities %A Cheung Wing-Sum %A Zhao Chang-Jian %J Journal of Inequalities and Applications %D 2007 %I Springer %X 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. %U http://www.journalofinequalitiesandapplications.com/content/2007/038347
