Groups with permutability conditions for subgroups of infinite rank [PDF]
International Journal of Group Theory, 2018 In this paper, the structure of non-periodic generalized radical groups of infinite rank whose subgroups of infinite rank satisfy a suitable permutability condition is investigated.

The Electronic Journal of Combinatorics, 2021 The concept of prolificity was previously introduced by the authors in the context of compositions of integers. We give a general interpretation of prolificity that applies across a range of relational structures defined in terms of counting embeddings.

Calculating Permutation Entropy without Permutations [PDF]
Complexity, 2020 A method for analyzing sequential data sets, similar to the permutation entropy one, is discussed. The characteristic features of this method are as follows: it preserves information about equal values, if any, in the embedding vectors; it is exempt from combinatorics; and it delivers the same entropy value as does the permutation method, provided the ...

Classification of finite groups with toroidal or projective-planar permutability graphs [PDF]
, 2015 Let $G$ be a group. The permutability graph of subgroups of $G$, denoted by $\Gamma(G)$, is a graph having all the proper subgroups of $G$ as its vertices, and two subgroups are adjacent in $\Gamma(G)$ if and only if they permute.

Bianchi permutability for the anti-self-dual Yang-Mills equations [PDF]
, 2016 The anti-self-dual Yang-Mills equations are known to have reductions to many integrable differential equations. A general B\"acklund transformation (BT) for the ASDYM equations generated by a Darboux matrix with an affine dependence on the spectral ...

A Proof Theoretic Analysis of Intruder Theories [PDF]
Logical Methods in Computer Science, 2010 We consider the problem of intruder deduction in security protocol analysis: that is, deciding whether a given message M can be deduced from a set of messages Gamma under the theory of blind signatures and arbitrary convergent equational theories modulo ...

Vectorial Ribaucour Transformations for the Lame Equations [PDF]
, 1997 The vectorial extension of the Ribaucour transformation for the Lame equations of orthogonal conjugates nets in multidimensions is given. We show that the composition of two vectorial Ribaucour transformations with appropriate transformation data is ...

Finite Groups with $H_σ$-Permutably Embedded Subgroups [PDF]
Advances in Group Theory and Applications, 2017 Let $G$ be a finite group. Let $\sigma=\{\sigma_i|i\inI\}$ be a partition of the set of all primes $P$ and $n$ an integer. We write $\sigma(n) = \{\sigma_i|\sigma_i\cap \pi(n)\neq\emptyset\}$, $\sigma(G) = \sigma(|G|)$.
