“…To show that entropy is preserved, we show (41) with the equality, using the Tadmor jump condition, (A.11). For each component, The penalty terms are therefore proportional to the difference between an entropy conserving flux for the specific system of equations and the conservative flux, rather than being directly proportional to the difference in the states, as was the case for linear problems considered in Paper I [14]. In the case of the Burgers equation, however, we show in the following example that the penalty terms can be written that way, but with a solution-dependent coefficient that depends on the two states.…”
