duality result with only one multiplier

{\bf COROLLARY}
\[
\bar{h}(\lambda) = -(-\lambda)_+  \alpha + (\lambda)_+
 \beta - \psi^t (B-\lambda C )^{\dagger} \psi,
\]
where
$$(\lambda)_+ = \left\{ \begin{array}{cc}
                      \lambda & {\mbox if~} \lambda \geq 0 \\
                      0 & \mbox{ otherwise.}
     \end{array} \right. $$
Then
\[
\mu^* = \max_{B-\lambda C > 0} \bar{h}(\lambda).
