Summary: We present a new lower bound on the minimum eigenvalue of \(H\)-matrices involving Hadamard products \(\tau(A_1^{(\alpha_1)} \circ \cdots \circ A_m^{(\alpha_m)})\), and we show that our lower bound is larger than the lower bound \(\prod_{k=1}^m[\tau(A_k)]^{\alpha_k}\). Three examples verify our result.
