A class of solutions of the equation d(n²) = d(φ(n)) [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
For any positive integer n let d(n) and φ(n) be the number of divisors of n and the Euler's phi function of n, respectively. In this paper we present some notes on the equation d(n²) = d(φ(n)).

The mean value of the function d(n)/d*(n) in arithmetic progressions [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
Let d(n) and d*(n) be, respectively, the number of divisors and the number of unitary divisors of an integer n≥1. A divisor d of an integer is to be said unitary if it is prime over n/d.

All basic quantizations of $$D=3$$ D = 3 , $$N=1$$ N = 1 Lorentz supersymmetry

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
By the supersymmetrization of a simple algebraic technique proposed in Lukierski and Tolstoy (Eur Phys J C 77:226, 2017) we obtain the complete classification of all basic (nonisomorphic) quantum deformations for the orthosymplectic Lie superalgebra ...

Микротопонимы городa-завода Ижевск как источник изучения его удмуртской предыстории [Microtoponyms of the City-Factory of Izhevsk as a Source for Study of its Udmurt Prehistory] [PDF]

open access: yesLinguistica Uralica, 2021
The present article aims to study the microtoponyms of Izhevsk in a wide historical and cultural context in order to consider the content of the Udmurt component in the city’s prehistory. Special attention is paid to the etymology of hydronyms (Иж, К

$$\theta $$ θ -diagram technique for $${\mathcal {N}}=1$$ N = 1 , $$d=4$$ d = 4 superfields

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We describe a diagrammatic procedure to carry out the Grassmann integration in super-Feynman diagrams of 4d theories expressed in terms of $${\mathcal {N}}=1$$ N = 1 superfields. This method is alternative to the well known D-algebra approach. We develop

Conformal manifolds and 3d mirrors of (D n , D m ) theories

open access: yesJournal of High Energy Physics, 2022
The Argyres-Douglas (AD) theories of type (D n , D m ), realized by type IIB geometrical engineering on a single hypersurface singularity, are studied. We analyze their conformal manifolds and propose the 3d mirror theories of all theories in this class ...

Gauged D = 4 N $$ \mathcal{N} $$ = 4 supergravity

open access: yesJournal of High Energy Physics, 2023
We present the full Lagrangian and supersymmetry transformation rules for the gauged D = 4, N $$ \mathcal{N} $$ = 4 (half-maximal) supergravity coupled to an arbitrary number of vector multiplets. Using the embedding tensor formulation, the final results
