Dynamic Complexity of Parity Exists Queries [PDF]

open access: yesLogical Methods in Computer Science, 2021
Given a graph whose nodes may be coloured red, the parity of the number of red nodes can easily be maintained with first-order update rules in the dynamic complexity framework DynFO of Patnaik and Immerman.

The Arity Hierarchy in the Polyadic μ-Calculus [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
The polyadic mu-calculus is a modal fixpoint logic whose formulas define relations of nodes rather than just sets in labelled transition systems. It can express exactly the polynomial-time computable and bisimulation-invariant queries on finite graphs ...

On the Mints Hierarchy in First-Order Intuitionistic Logic [PDF]

open access: yesLogical Methods in Computer Science, 2017
We stratify intuitionistic first-order logic over $(\forall,\to)$ into fragments determined by the alternation of positive and negative occurrences of quantifiers (Mints hierarchy). We study the decidability and complexity of these fragments.

Polyadic Hopf Algebras and Quantum Groups

open access: yesEast European Journal of Physics, 2021
This article continues the study of concrete algebra-like structures in our polyadic approach, where the arities of all operations are initially taken as arbitrary, but the relations between them, the arity shapes, are to be found from some natural ...

The Mask of Odd Points n-Ary Interpolating Subdivision Scheme

open access: yesJournal of Applied Mathematics, 2012
We present an explicit formula for the mask of odd points n-ary, for any odd n⩾3, interpolating subdivision schemes. This formula provides the mask of lower and higher arity schemes. The 3-point and 5-point a-ary schemes introduced by Lian, 2008, and (2m+

Essential Arity Gap of Boolean Functions [PDF]

open access: yes, 2008
In this paper we investigate the Boolean functions with maximum essential arity gap. Additionally we propose a simpler proof of an important theorem proved by M. Couceiro and E. Lehtonen in [3].

Some simple varieties of trees arising in permutation analysis [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
After extending classical results on simple varieties of trees to trees counted by their number of leaves, we describe a filtration of the set of permutations based on their strong interval trees.

Multiary Gradings

open access: yesAxioms
This article develops a comprehensive theory of multiary graded polyadic algebras, extending the classical concept of group-graded algebras to higher-arity structures.

Understanding and Mitigating the Risk of Accelerated Biological Aging in Survivors of Cancer: A Scoping Review

open access: yesAging and Cancer, EarlyView.
Cancer treatment is associated with measurable acceleration of biological aging across epigenetic, telomere, senescence, and immune biomarkers. However, biomarker validation and interventional strategies remain limited, especially in hematologic malignancies, underscoring the need for standardized multi‐omic aging assessments and adequately powered ...
