Query: Minimax Observers for Linear DAEs   In this note we construct minimax observers for linear stationary DAEs with
bounded uncertain inputs, given noisy measurements. We prove a new duality
principle and show that a finite (infinite) horizon minimax observer exists if
and only if the DAE is $\ell$-impulse observable ($\ell$-detectable) .
Remarkably, the regularity of the DAE is not required.
