Lozano, C. 2018. Entropy Production by Explicit Runge-Kutta Schemes. Journal of Scientific Computing 76, 1, 521-564, DOI: 10.1007/s10915-017-0627-0
We propose and test a formula for the separate computation of the temporal and spatial entropy production of fully discrete, finite-volume, explicit Runge-Kutta discretizations of systems of conservation laws.
