Proving theorems by program transformation [PDF]

open access: yes, 2013
In this paper we present an overview of the unfold/fold proof method, a method for proving theorems about programs, based on program transformation. As a metalanguage for specifying programs and program properties we adopt constraint logic programming ...

On decisions of Schwartz' problem for J-analytic functions with the same Jordan basis of real and imaginary parts of J-matrix

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2016
Boundary Schwartz' problem for J-analytic functions was studied within this scientific work. These functions are solutions of linear complex system of partial differential equations of the first order. It was considered, that the real and imaginary parts

Automated verification of refinement laws [PDF]

open access: yes, 2009
Demonic refinement algebras are variants of Kleene algebras. Introduced by von Wright as a light-weight variant of the refinement calculus, their intended semantics are positively disjunctive predicate transformers, and their calculus is entirely within ...

Factorization at subleading power and endpoint divergences in h → γγ decay. Part II. Renormalization and scale evolution

open access: yesJournal of High Energy Physics, 2021
Building on the recent derivation of a bare factorization theorem for the b-quark induced contribution to the h → γγ decay amplitude based on soft-collinear effective theory, we derive the first renormalized factorization theorem for a process described ...

Toward the Formalization of Macroscopic Models of Traffic Flow Using Higher-Order-Logic Theorem Proving

open access: yesIEEE Access, 2020
Next-generation transportation will be integrated, interconnected and highly autonomous. One key challenge in traffic management is ensuring safety while maintaining the required level of service quality.

New bound for Roth's theorem with generalized coefficients

open access: yesDiscrete Analysis, 2022
New bound for Roth's theorem with generalized coefficients, Discrete Analysis 2022:16, 21 pp. Roth's theorem states that for every $\delta>0$ there exists $n$ such that every subset of $\{1,2,\dots,n\}$ of size at least $\delta n$ contains an arithmetic

Reasoning in the OWL 2 Full Ontology Language using First-Order Automated Theorem Proving

open access: yes, 2011
OWL 2 has been standardized by the World Wide Web Consortium (W3C) as a family of ontology languages for the Semantic Web. The most expressive of these languages is OWL 2 Full, but to date no reasoner has been implemented for this language.

The postulations á la D'Alembert and á la Cauchy for higher gradient continuum theories are equivalent. A review of existing results [PDF]

open access: yes, 2015
In order to found continuum mechanics, two different postulations have been used. The first, introduced by Lagrange and Piola, starts by postulating how the work expended by internal interactions in a body depends on the virtual velocity field and its ...

Quenched vs Annealed: Glassiness from SK to SYK

open access: yesPhysical Review X, 2020
We show that any Sachdev-Ye-Kitaev- (SYK) like model with finite-body interactions among local degrees of freedom, e.g., bosons or spins, has a fundamental difference from the standard fermionic model: The former model fails to be described by an ...

Graph Representations for Higher-Order Logic and Theorem Proving

open access: yes, 2019
This paper presents the first use of graph neural networks (GNNs) for higher-order proof search and demonstrates that GNNs can improve upon state-of-the-art results in this domain.
