Generalizations of H?lder's inequality
Wing-Sum Cheung
International Journal of Mathematics and Mathematical Sciences , 2001, DOI: 10.1155/s0161171201005658
Abstract: Some generalized Hölder's inequalities for positive as well as negative exponents are obtained.
Some discrete Poincaré-type inequalities
Wing-Sum Cheung
International Journal of Mathematics and Mathematical Sciences , 2001, DOI: 10.1155/s0161171201005403
Abstract: Some discrete analogue of Poincaré-type integral inequalities involving many functions of many independent variables are established. These in turn can serve as generators of further interesting discrete inequalities.
Interval oscillation criteria for second-order forced delay differential equations under impulse effects
Qiaoluan Li,Wing-Sum Cheung
Electronic Journal of Differential Equations , 2013,
Abstract: We establish some oscillation criteria for a forced second-order differential equation with impulses. These results extend some well-known results for forced second-order impulsive differential equations with delay.
On Inverse Hilbert-Type Inequalities
Changjian Zhao,Cheung Wing-Sum
Journal of Inequalities and Applications , 2008,
Abstract: This paper deals with new inverse-type Hilbert inequalities. Our results in special cases yield some of the recent results and provide some new estimates on such types of inequalities.
On Ostrowski-Type Inequalities for Higher-Order Partial Derivatives
Changjian Zhao,Cheung Wing-Sum
Journal of Inequalities and Applications , 2010,
Abstract: We establish some new Ostrowski-type integral inequalities involving higher-order partial derivatives. As applications, we get some interrelated results. Our results provide new estimates on inequalities of this type.

Note on weighted Carleman-type inequality
Chao-Ping Chen,Wing-Sum Cheung,Feng Qi
International Journal of Mathematics and Mathematical Sciences , 2005, DOI: 10.1155/ijmms.2005.475
Abstract: A double inequality involving the constant e is proved by using an inequality between the logarithmic mean and arithmetic mean. As an application, we generalize the weighted Carleman-type inequality.
An Opial-Type Inequality on Time Scales
Qiao-Luan Li,Wing-Sum Cheung
Abstract and Applied Analysis , 2013, DOI: 10.1155/2013/534083
Abstract:
Some new nonlinear retarded sum-difference inequalities with applications
Wang Wu-Sheng,Li Zizun,Cheung Wing-Sum
Advances in Difference Equations , 2011,
Abstract: The main objective of this paper is to establish some new retarded nonlinear sum-difference inequalities with two independent variables, which provide explicit bounds on unknown functions. These inequalities given here can be used as handy tools in the study of boundary value problems in partial difference equations. 2000 Mathematics Subject Classification: 26D10; 26D15; 26D20.
