Finite rings with some restrictions on zero-divisor graphs

Publikováno v: Russian Mathematics. 58:41-50

The zero-divisor graph Γ(R) of an associative ring R is the graph whose vertices are all nonzero zero-divisors (one-sided and two-sided) of R, and two distinct vertices x and y are joined by an edge if and only if either xy = 0 or yx = 0.

The description of varieties of rings whose finite rings are uniquely determined by their zero-divisor graphs

Autor: E. V. Zhuravlev, Yu. N. Mal'tsev, A. S. Kuz’mina

Publikováno v: Russian Mathematics. 57:10-20

The zero-divisor graph of an associative ring R is defined as follows. The vertices of the graph are all the nonzero elements of the ring. Two different vertices x and y of the graph are connected by an edge if and only if xy = 0 or yx = 0.

Describing ring varieties in which all finite rings have Hamiltonian zero-divisor graphs

Autor: A. S. Kuz’mina, Yu. N. Mal'tsev

Publikováno v: Algebra and Logic. 52:137-146

The zero-divisor graph of an associative ring R is a graph such that its vertices are all nonzero (one-sided and two-sided) zero-divisors, and moreover, two distinct vertices x and y are joined by an edge iff xy = 0 or yx = 0. We give a complete desc

Mössbauer studies of the surface and bulk properties of substituted iron-garnet films in the vicinity of the Curie point

Autor: A. S. Kamzin, Yu. N. Mal’tsev

Publikováno v: Physics of the Solid State. 39:1251-1254

The magnetic properties of the surface layer and bulk of iron-garnet films of composition Y2.6Sm0.4Fe3.7Ga1.3O12, grown by liquid-phase epitaxy on substrates of a gadolinium-gallium garnet single crystal, are investigated. The method of simultaneous

On varieties of rings whose finite rings are determined by their zero-divisor graphs

Autor: Yu. N. Mal'tsev, A. S. Kuz’mina

The zero-divisor graph $\Gamma(R)$ of an associative ring $R$ is the graph whose vertices are all nonzero zero-divisors (one-sided and two-sided) of $R$, and two distinct vertices $x$ and $y$ are joined by an edge iff either $xy=0$ or $yx=0$. In the
