The Additive Logic of Epistemic Reasons: An Axiomatic Account

open access: yesTheoria, EarlyView.
ABSTRACT The article argues for a system of axioms that is meant to capture the logic of normative reasons for belief. The system concerns a primitive direct‐reason relation, a defined doxastic‐reason relation, and a primitive function for the revision of rational belief by reasons.

Active Learning With a STEM Exercise Pool for Schools and Universities

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The STEM Exercise Pool is a digital, interactive teaching and learning resource for mathematics education in the first year of STEM and teacher training degree programs, as well as for upper secondary school. Developed by a team of experts from several universities, it comprises nearly one thousand quality‐reviewed tasks featuring automatic ...

Context‐free graphs and their transition groups

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Starting from context‐free inverse graphs, we introduce a new class of groups and study their structural properties. We establish closure properties, show that their coword problems are context‐free, analyze torsion elements, and realize them as subgroups of the asynchronous rational group.

Concurrency and automata on infinite sequences [PDF]

open access: yes
The paper is concerned with ways in which fair concurrency can be modeled using notations for omega-regular languages - languages containing infinite sequences, whose recognizers a.re modified forms of Buchi or Muller-McNaughton automata.

An algebraic theory of ω-regular languages, via μν-expressions [PDF]

open access: yes
Alternating parity automata (APAs) provide a robust formalism for modelling infinite behaviours and play a central role in formal verification. Despite their widespread use, the algebraic theory underlying APAs has remained largely unexplored.

A Common External Framework for Kleene and McCarthy Algebras

open access: yesMathematical Logic Quarterly, Volume 72, Issue 4, November 2026.
ABSTRACT Algebras of disjoint alternatives (ADAs), introduced by Manes, are extensions of McCarthy algebras by a unary operator acting as an oracle for the halting problem, and provide a semantics for the equational theory of the if–then–else construct.

Applications of algebraic automata theory to quantum finite automata

open access: yes, 2007
The computational model of Quantum Finite Automata has been introduced by multiple authors (e.g. [38, 44]) with some variations in definition. The objective of this thesis is to understand what class of languages can be recognized by these different ...

ManyBabies 3: A Multi‐Lab Study of Infant Algebraic Rule Learning

open access: yesDevelopmental Science, Volume 29, Issue 6, November 2026.
ABSTRACT The ability to learn and apply rules lies at the heart of cognition. In a seminal study, Marcus et al. (1999) reported that 7‐month‐old infants learned abstract rules over syllable sequences and were able to generalize those rules to novel syllable sequences.
