Abstract
<abstract><p>In this study, we generalize the definition of the Fan product of two <italic>M</italic>-matrices to any $ k $ <italic>M</italic>-matrices $ {{A}_{1}}, {{A}_{2}}, \cdots, {{A}_{k}} $ of order $ n $. We introduce two new inequalities for the lower bound of the minimum eigenvalue $ \tau \left({{A}_{1}}\star {{A}_{2}}\star \cdots \star {{A}_{k}} \right) $. These new lower bounds generalize the existing results. To validate the accuracy of our findings, we present examples in which our results outperform previous ones in certain cases.</p></abstract>
