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 ...

Answer Counting under Guarded TGDs [PDF]

open access: yesLogical Methods in Computer Science, 2023
We study the complexity of answer counting for ontology-mediated queries and for querying under constraints, considering conjunctive queries and unions thereof (UCQs) as the query language and guarded TGDs as the ontology and constraint language ...

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+

Arity hierarchies

open access: yesAnnals of Pure and Applied Logic, 1996
For many extensions \(L\) of first-order logic considered for finite structures there is a natural notion of arity of a formula (e.g., the maximal arity of a bounded second-order variable in a formula of fixed-point logic). Denote by \(L^k\) the fragment of \(L\) consisting of the sentences of \(L\) of arity \(\leq k\).

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.

The minimal arity of near unanimity polymorphisms [PDF]

open access: yesMathematica Slovaca, 2019
Abstract Dmitriy Zhuk has proved that there exist relational structures which admit near unanimity polymorphisms, but the minimum arity of such a polymorphism is large and almost matches the known upper bounds. We present a simplified and explicit construction of such structures and a detailed, self–contained proof.

Green’s Relations on Submonoids of Generalized Hypersubstitutions of Type (n)

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2021
A generalized hypersubstitution of type τ = (n) is a function which takes the n-ary operation symbol f to the term of the same type σ(f ) which does not necessarily preserve the arity. Let HypG(n) be the set of all these generalized hypersubstitutions of

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

open access: yesAdvanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.
