Abstract:

Using the construction theorem of the homogeneous kernel Hilbert-type integral inequality, a Hilbert-type integral inequality involving a variable upper limit integral function and a higher order derivative is discussed, and sufficient necessary conditions for constructing this inequality and an expression for the optimal constant factor are obtained, which generalizes and improves the existing results. Finally, the resulting Hilbert-type inequality is utilized to discuss the problems of boundedness and operator norm for the relevant integral operator.

Key words: variable upper limit integral function, higher-order derivative, Hilbert-type integral inequality, bounded integral operator, operator norm, Gamma function
