An ultraweak variational method for parameterized linear differential-algebraic equations
Emil Beurer, Moritz Feuerle, Niklas Reich +1
We investigate an ultraweak variational formulation for (parameterized) linear differential-algebraic equations (DAEs) w.r.t. the time variable which yields an optimally stable sys…
