Abstract. We address the general problem of automatically proving safety properties of reactive systems within the UNITY model. We take up a relational and set-based approach, and ...
1 We develop a learning component for a theorem prover designed for verifying statements by mathematical induction. If the prover has found a proof, it is analyzed yielding a so-ca...
We present Saharon Shelah's Stability Spectrum and Homogeneity Spectrum theorems, as well as the equivalence between the order property and instability in the framework of Fin...
The set of all orientations of a planar graph with prescribed outdegrees carries the structure of a distributive lattice. This general theorem is proven in the first part of the p...
We provide a much shorter proof of the following partition theorem of P. Erdos and R. Rado: If X is an uncountable linear order into which neither 1 nor 1 embeds, then X (, 4)3 f...
