Generalized nilpotent braces and nilpotent groups
Autor: Martyn Dixon, Leonid Kurdachenko, Igor Subbotin
Publikováno v: International Journal of Group Theory, Vol 14, Iss 1, Pp 25-45 (2023)
The authors give a brief survey of some results concerning nilpotent braces and their generalizations. Various results concerning $\star$-hypercentral and locally $\star$-nilpotent braces are given.

On the automorphism groups of some Leibniz algebras
Autor: Leonid Kurdachenko, Aleksand Pypka, Igor Subbotin
Publikováno v: International Journal of Group Theory, Vol 12, Iss 1, Pp 1-20 (2023)
We study the automorphism groups of finite-dimensional cyclic Leibniz algebras. In this connection, we consider the relationships between groups, modules over associative rings and Leibniz algebras.

On some generalization of the malnormal subgroups
Autor: Leonid Kurdachenko, Nikolai Semko, Igor Subbotin
Publikováno v: International Journal of Group Theory, Vol 9, Iss 1, Pp 7-24 (2020)
‎‎A subgroup $H$ of a group $G$ is called malonormal in $G$ if $H \cap H^x =\langle 1\rangle$ for every element $x \notin N_G(H)$‎. ‎These subgroups are generalizations of malnormal subgroups‎. ‎Every malnormal subgroup is malonormal‎,

Revision of the total nitrogen and phosphorus content in a cattle manure-based organic fertiliser in North-West Russia
Autor: Ekaterina Shalavina, Aleksandr Briukhanov, Sari Luostarinen, Alexey Trifanov, Natalia Kozlova, Eduard Vasilev, Igor Subbotin
Publikováno v: Agricultural and Food Science, Vol 30, Iss 2 (2021)
This study aimed to verify the applicability of a mass balance method for estimating nitrogen (N) and phosphorus (P) content in the solid organic fertiliser produced from cattle manure in North-West Russia. The study compared the relevant established

On the relationships between the factors of the upper and lower central series in some non-periodic groups
Autor: Martyn Dixon, Leonid Kurdachenko, Igor Subbotin
Publikováno v: International Journal of Group Theory, Vol 7, Iss 1, Pp 37-50 (2018)
This paper deals with the mutual relationships between the factor group $G/zeta(G)$ (respectively $G/zeta_k(G)$) and $G'$ (respectively $gamma_{k+1}(G)$ and $G^{mathfrak{N}}$). It is proved that if $G/zeta(G)$ (respectively $G/zeta_k(G)$) has finite

A Forecast Model of the Complex Negative Impact of Agricultural Production Technologies on Water Bodies
Autor: Eduard Vasilev, Igor Subbotin
Publikováno v: Инженерные технологии и системы, Vol 31, Iss 2, Pp 227-240 (2021)
Introduction. The purpose of research is to develop a mathematical model for assessing and forecasting the complex negative impacts of agricultural technologies on water bodies. This problem is relevant because of the need to enlarge agricultural ent
