report
We construct a local invariant for resolution of singularities of 2-dimensional excellent Noetherian schemes with boundary. We prove that the invariant strictly decreases at every step of the algorithm of Cossart, Jannsen and Saito.
Comment: 41 pages, improved exposition, clarified minor details, added section of the termination of the CJS algorithm
