Summary: Let \(\nu\) be a positive measure on a space \(Y\) with \(\nu(Y)\neq 0\) and let \(f_j\) \((j= 1,2,\dots, n)\) be positive \(\nu\)-integrable functions on \(Y\). For some positive real numbers \(\alpha_j\) \((j= 1,2,\dots, n)\), \(\beta_j\) \((j= 1,2,\dots, k< n)\) and a measurable subset \(Y_1\) of \(Y\), we state some inequalities. From these results, we refine Hölder’s inequality.
