On Non-Archimedean Fuzzy Metric Free Topological Groups

open access: yesAxioms
We construct the free group over a non-Archimedean fuzzy metric space (X,M,∧) in the sense of George and Veeramani where ∧ is the minimum t-norm. The two main tools used are the concept of a scheme (for every non-empty subset S of N of even cardinal, a ...

In vitro studies on the antimicrobial, antioxidant and antidiabetic potential of Cephalaria gigantea

open access: yesBangladesh Journal of Pharmacology, 2015
This study evaluates the antimicrobial, antioxidant and antidiabetic potential of leaf and root extracts of Cephalaria gigantea. The results showed that the extracts inhibited both bacteria and fungi tested at MIC values which ranged from 3.1 to 12.5 mg ...

Effectiveness of mycofiltration for removal of contaminants from water: a systematic review protocol

open access: yesEnvironmental Evidence, 2021
Background Mycofiltration is an environment friendly technology which involves the treatment of contaminated water by passing it through a network of fungal mycelium. This technology has gained momentum over the years, and the systematic review chartered

A Carbon Reduction and Waste Heat Utilization Strategy for Generators in Scalable PV—Diesel Generator Campus Microgrids

open access: yesEnergies, 2023
The increased unavailability of electricity from the National Utility in South Africa, coupled with the extreme conditions of rural areas and general lack of infrastructure, leads to the setup of unique microgrids to utilize the conditions available. One

On the generic type of the free group [PDF]

open access: yesJournal of Symbolic Logic (JSL), 2010
We answer a question raised in [9], that is whether the infinite weight of the generic type of the free group is witnessed in Fω. We also prove that the set of primitive elements in finite rank free groups is not uniformly definable.

What does a group algebra of a free group know about the group?

open access: yes, 2018
We describe solutions to the problem of elementary classification in the class of group algebras of free groups. We will show that unlike free groups, two group algebras of free groups over infinite fields are elementarily equivalent if and only if the ...

Fueling Toxicity? Studying Deceitful Opinion Leaders and Behavioral Changes of Their Followers

open access: yesPolitics and Governance, 2022
The spread of deceiving content on social media platforms is a growing concern amongst scholars, policymakers, and the public at large. We examine the extent to which influential users (i.e., “deceitful opinion leaders”) on Twitter engage in the spread ...

Homological finiteness in the Johnson filtration of the automorphism group of a free group [PDF]

open access: yes, 2010
We examine the Johnson filtration of the (outer) automorphism group of a finitely generated group. In the case of a free group, we find a surprising result: the first Betti number of the second subgroup in the Johnson filtration is finite.

Free group automorphisms with many fixed points at infinity [PDF]

open access: yes, 2009
A concrete family of automorphisms alpha_n of the free group F_n is exhibited, for any n > 2, and the following properties are proved: alpha_n is irreducible with irreducible powers, has trivial fixed subgroup, and has 2n-1 attractive as well as 2n ...

Free Quantum Fields on the Poincare' Group

open access: yes, 1996
A class of free quantum fields defined on the Poincare' group, is described by means of their two-point vacuum expectation values. They are not equivalent to fields defined on the Minkowski spacetime and they are "elementary" in the sense that they ...
