We give a short proof of a lemma which generalizes both the main lemma from the original construction in the author's thesis of a model with no 2-Aronszajn trees, and also th...
This paper puts forward a new notion of a proof based on computational complexity and explores its implications for computation at large. Computationally sound proofs provide, in a...
This paper presents a machine-checked proof of the Basic Theorem on Concept Lattices, which appears in the book “Formal Concept Analysis” by Ganter and Wille, in the Isabelle/H...
The paper presents a modular superposition calculus for the combination of firstorder theories involving both total and partial functions. The modularity of the calculus is a cons...
