Query: Stability analysis of delay differential equations via Semidefinite
  programming   This paper studies the problem of stability of a parameterized delay
differential equations (DDE see equation (0.1)). After discretizing the DDE
(0.1), we show that the problem can be equivalently casted into a semi-definite
programming (SDP) see (3.2), which can be solved efficiently through some
popular algorithm, e.g., the interior point method [1].
