About Periodic Shunkov Group Saturated with Finite Simple Groups of Lie Type Rank 1

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2016
The property of group G to be saturated with given set of groups X is a natural generalization of locally-cover definition (in class of locally finite groups) on periodic groups. Locally-finite group, witch has a locally-cover contains from finite simple

Zoology of Atlas-Groups: Dessins D’enfants, Finite Geometries and Quantum Commutation

open access: yesMathematics, 2017
Every finite simple group P can be generated by two of its elements. Pairs of generators for P are available in the Atlas of finite group representations as (not necessarily minimal) permutation representations P .

Photonic Engineering Enables All‐Passive Upconversion Imaging with Low‐Intensity Near‐Infrared Light

open access: yesAdvanced Functional Materials, EarlyView.
A passive upconversion imaging system enables the observation of scenes illuminated by low‐intensity incoherent near‐infrared light from 750 to 930 nm, by converting it into the visible without the use of external power. The upconverter is enabled by triplet–triplet annihilation in a bulk heterojunction, with absorption enhanced by plasmonic resonators

Attempts to use the power of modern group theory in finite simple groups for calculating Galois groups

open access: yesLe Matematiche, 2000
This is the text of my lectures in Catania (Sicily) in April 2001, and at a Group Theory Conference in Oberwohlfach (Germany) in April 1997. The Catania visit was in honor of the 60-th birthday of my good friend Sylvio Greco.

Introduction to Sporadic Groups

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
This is an introduction to finite simple groups, in particular sporadic groups, intended for physicists. After a short review of group theory, we enumerate the 1+1+16=18 families of finite simple groups, as an introduction to the sporadic groups.

Finite simple groups with number of zeros slightly greater than the number of nonlinear irreducible characters [PDF]

open access: yesInternational Journal of Group Theory, 2012
The aim of this paper is to classify the finite simple groups with the number of zeros at most seven greater than the number of nonlinear irreducible characters in the character tables. We find that they are exactly A$_{5}$, L$_{2}(7)$ and A$_{6}$.

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Generators for maximal subgroups of Conway group Co1

open access: yesOpen Mathematics, 2019
The Conway groups are the three sporadic simple groups Co1, Co2 and Co3. There are total of 22 maximal subgroups of Co1 and generators of 6 maximal subgroups are provided in web Atlas of finite simple groups.
