Brauer relations in finite groups [PDF]

open access: yes, 2015
If G is a non-cyclic finite group, non-isomorphic G-sets X, Y may give rise to isomorphic permutation representations C[X] and C[Y]. Equivalently, the map from the Burnside ring to the representation ring of G has a kernel. Its elements are called Brauer

The cancellation norm and the geometry of bi-invariant word metrics

open access: yes, 2016
We study biinvariant word metrics on groups. We provide an efficient algorithm for computing the biinvariant word norm on a finitely generated free group and we construct an isometric embedding of a locally compact tree into the biinvariant Cayley graph ...

On Groups in Which Many Automorphisms Are Cyclic

open access: yesMathematics, 2022
Let G be a group. An automorphism α of G is said to be a cyclic automorphism if the subgroup ⟨x,xα⟩ is cyclic for every element x of G. In [F. de Giovanni, M.L. Newell, A. Russo: On a class of normal endomorphisms of groups, J.

Testing the Clar theory: Cyclic conjugation in some benzo- and naphthaleno-annelated ovalenes [PDF]

open access: yesKragujevac Journal of Science, 2014
Cyclic conjugation (assessed by its energy effect) is studied in benzo- and naphthaleno-annelated ovalenes, in which annelation is in positions d and o.

Enhancing fluorescence and lowering the optical gap through CP doping of a π-conjugated molecular backbone: A computational-based design approach

open access: yesJournal of Photochemistry and Photobiology, 2021
Design principles of organic fluorescent materials are investigated at the molecular level using a first-principles-based computational approach. The design approach incorporates hetero atoms into a conjugated cyclic skeleton by introducing CP bonds. In

Ultrasound-sensitive cRGD-modified liposomes as a novel drug delivery system

open access: yesArtificial Cells, Nanomedicine, and Biotechnology, 2022
Targeted liposomes enable the delivery of encapsulated chemotherapeutics to tumours by targeting specific receptors overexpressed on the surfaces of cancer cells; this helps in reducing the systemic side effects associated with the cytotoxic agents. Upon

Cyclic conjugation in benzo-annelated triphenylenes [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
Cyclic conjugation in benzo-annelated triphenylenes was studied by means of the energy effect (ef) and the π-electron content (EC) of the six-membered rings.

Modulating Protein–Protein Interactions by Cyclic and Macrocyclic Peptides. Prominent Strategies and Examples

open access: yesMolecules, 2021
Cyclic and macrocyclic peptides constitute advanced molecules for modulating protein–protein interactions (PPIs). Although still peptide derivatives, they are metabolically more stable than linear counterparts, and should have a lower degree of ...

Uniformization of Deligne-Mumford curves [PDF]

open access: yes, 2005
We compute the fundamental groups of non-singular analytic Deligne-Mumford curves, classify the simply connected ones, and classify analytic Deligne-Mumford curves by their uniformization type.

Infinity-Norm Permutation Covering Codes from Cyclic Groups

open access: yes, 2017
We study covering codes of permutations with the $\ell_\infty$-metric. We provide a general code construction, which uses smaller building-block codes.
