TY - JOUR AU - Cheng, Ada PY - 2006 TI - Well-Posedness of Second Order Uniformly Elliptic Boundary Control Systems with Additive or Multiplicative Uncertainty JF - Journal of Mathematics and Statistics VL - 2 IS - 4 DO - 10.3844/jmssp.2006.442.444 UR - https://thescipub.com/abstract/jmssp.2006.442.444 AB - Boundary control systems arises naturally in many applications. Any modelling of real systems involve uncertainty. Sufficient conditions for well-posededness for additive or multiplicative uncertainty are presented through the use of matrix theory.
