Equivalences for pattern avoiding involutions and classification [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We complete the Wilf classification of signed patterns of length 5 for both signed permutations and signed involutions. New general equivalences of patterns are given which prove Jaggard's conjectures concerning involutions in the symmetric group ...

Involutions on Baxter Objects [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
Baxter numbers are known to count several families of combinatorial objects, all of which come equipped with natural involutions. In this paper, we add a combinatorial family to the list, and show that the known bijections between these objects respect ...

Involutions with fixed point set Dold manifold P(2,15) [PDF]

open access: yesJournal of Hebei University of Science and Technology, 2023
In order to study the equivariant cobordism classification of involutions with fixed point set Dold manifolds, for a special Dold manifold F=P(2,15), the equivariant cobordism classification of all involutions (M,T) with fixed point set was determined ...

Enumeration of Neutrosophic Involutions over Finite Commutative Neutrosophic Rings [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
A finite commutative ring involution is the multiplicative inverse of the element attribute R is the element itself. This classical characteristic of a finite commutative ring makes Neutrosophic involutions possible, which are counted, listed and ...

Enumeration of Involutions of Finite Rings

open access: yesJournal of New Theory, 2021
In this paper, we study a special class of elements in the finite commutative rings called involutions. An involution of a ring R is an element with the property that x^2-1=0 for some x in R.

Orientifold Calabi-Yau threefolds with divisor involutions and string landscape

open access: yesJournal of High Energy Physics, 2022
We establish an orientifold Calabi-Yau threefold database for h 1,1(X) ≤ 6 by considering non-trivial ℤ2 divisor exchange involutions, using a toric Calabi-Yau database ( www.rossealtman.com/tcy ).

On Generation of the Groups $SL_n(\mathbb{Z}+i\mathbb{Z})$ and $PSL_n(\mathbb{Z}+i\mathbb{Z})$ by Three Involutions, Two of Which Commute

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2022
M. C. Tamburini and P. Zucca proved that the special linear group of dimension greater than 13 over the ring of Gaussian integers is generated by three involutions, two of which commute (J. of Algebra, 1997).

Asymptotic distribution of fixed points of pattern-avoiding involutions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2017
For a variety of pattern-avoiding classes, we describe the limiting distribution for the number of fixed points for involutions chosen uniformly at random from that class.

Refined dual stable Grothendieck polynomials and generalized Bender-Knuth involutions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
The dual stable Grothendieck polynomials are a deformation of the Schur functions, originating in the study of the K-theory of the Grassmannian. We generalize these polynomials by introducing a countable family of additional parameters such that the ...

Small-scale geologic evidence for Vistulian decline cooling periods: case studies from the Łódź Region (Central Poland) [PDF]

open access: yesBulletin of the Geological Society of Finland, 2018
This study concerns small-scale features in the form of denivation structures, periglacial involutions, sharp-edged blocks, fragipan layers and frost fissures observed in various depositional environments of Central Poland. These are terrestrial evidence
