Compressed zero-divisor graphs of noncommutative rings
Alen Đurić, Sara Jevđenić, Nik Stopar
We extend the notion of the compressed zero-divisor graph to noncommutative rings in a way that still induces a product preserving functor from the categ…
Heisenberg model in pseudo-Euclidean spaces II
Bozidar Jovanovic, Vladimir Jovanovic
In the review we describe a relation between the Heisenberg spin chain model on pseudospheres and light--like cones in pseudo--Eucli\-dean spaces and virtual billiards. A geometric…
Categorial properties of compressed zero-divisor graphs of finite commutative rings
Alen Đurić, Sara Jevđenić, Nik Stopar
We define a compressed zero-divisor graph of a finite commutative unital ring , where the compression is performed by means of the associatedness relation. We pro…
Variable neighborhood search for partitioning sparse biological networks into the maximum edge-weighted -plexes
Milana Grbić, Aleksandar Kartelj, Savka Janković +2
In a network, a -plex represents a subset of vertices where the degree of each vertex in the subnetwork induced by this subset is at least . The maximum edge-weight …
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
Semi-flexible compact polymers in two dimensional nonhomogeneous confinement
D Marčetić, S Elezović-Hadžić, N Adžić +1
We have studied the compact phase conformations of semi-flexible polymer chains confined in two dimensional nonhomogeneous media, modelled by fractals that belong to the family of…
Long-term monitoring of the broad-line region properties in a selected sample of AGN
Dragana Ilic, Alla I. Shapovalova, Luka C. Popovic +8
We present the results of the long-term optical monitoring campaign of active galactic nuclei (AGN) coordinated by the Special Astrophysical Observatory of the Russian Academy of S…
On Enumeration of Dyck Paths with colored hills
Milan Janjic
We continue to investigate the properties of the earlier defined functions fm and gm, which depend on an initial arithmetic function f0. In this papers values of f0 are the Fine nu…
The total zero-divisor graph of commutative rings
Alen Đurić, Sara Jevđenić, Polona Oblak +1
In this paper we initiate the study of the total zero-divisor graphs over commutative rings with unity. These graphs are constructed by both relations that arise from the zero-divi…
