Completeness for the coalgebraic cover modality [PDF]
We study the finitary version of the coalgebraic logic introduced by L. Moss. The syntax of this logic, which is introduced uniformly with respect to a coalgebraic type functor, required to preserve weak pullbacks, extends that of classical propositional

Galois coverings of selfinjective algebras by repetitive algebras [PDF]
Let \(A\) be a basic and connected selfinjective Artin algebra. Then the right and the left socles of \(A\) coincide and are denoted by \(\text{soc }A\). Two selfinjective algebras \(A\) and \(A'\) are called socle-equivalent if the quotient algebras \(A/\text{soc} A\) and \(A'/\text{soc} A'\) are isomorphic.

Lie algebras and coverings [PDF]
Let \(\Lambda\) be an associative unitary finite-dimensional \(\mathbb{C}\)-algebra which is representation finite. This means that the number of isomorphism classes of indecomposable finite-dimensional \(\Lambda\)-left modules is finite. Let us fix a set \(\mathcal F\) of representatives for these isomorphism classes. We showed [\textit{C. Riedtmann},

MONITORING OF AEROTECHNOGENIC IMPACT OF SYKTYVKAR TIMBER INDUSTRY COMPLEX
The relevance of the research is caused by the need to assess the level of impact of a large pulp and paper enterprise located north of the Ezhvinsky district of Syktyvkar on the basis of ecochemical analysis of winter precipitation (snow), to show the ...

LAND COVER CHANGE DETECTION BASED ON GENETICALLY FEATURE AELECTION AND IMAGE ALGEBRA USING HYPERION HYPERSPECTRAL IMAGERY [PDF]
The Earth has always been under the influence of population growth and human activities. This process causes the changes in land use. Thus, for optimal management of the use of resources, it is necessary to be aware of these changes.

Koszulness, Krull Dimension and Other Properties of Graph-Related Algebras [PDF]
The algebra of basic covers of a graph G, denoted by \A(G), was introduced by Juergen Herzog as a suitable quotient of the vertex cover algebra. In this paper we show that if the graph is bipartite then \A(G) is a homogeneous algebra with straightening ...

Carrollian and celestial spaces at infinity
We show that the geometry of the asymptotic infinities of Minkowski spacetime (in d + 1 dimensions) is captured by homogeneous spaces of the Poincaré group: the blow-ups of spatial (Spi) and timelike (Ti) infinities in the sense of Ashtekar-Hansen and a ...
