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

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

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]
Linguistica 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 cityâs prehistory. Special attention is paid to the etymology of hydronyms (Ðж, Ð

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

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

Carbon target as neutron source from 12C(d,n)13N and D(d,n)3He reactions
Ядерна фізика та енергетика, 2018 Possibility to use carbon as a target material to generate fast neutrons from D(d,n)3He nuclear reaction and intermediate energy neutrons from 12C(d,n)13N nuclear reaction was studied. The experiment results were obtained to characterize an adsorption of

N-(1-Deoxy-α-d-tagatopyranos-1-yl)-N-methylaniline (“d-Tagatose-N-methylaniline”)
Molbank, 2018 Tagatosamines form in thermally-processed dairy products and contribute to the foods’ organoleptic and nutritional value. d-Tagatose-N-methylaniline (N-(1-deoxy-d-tagatos-1-yl)-N-methylaniline, 1-deoxy-1-(N-methylphenylamino)-d-tagatose) was synthesized ...

D and N are different nominalizers
Glossa, 2020 In this paper I argue for a split between NP and DP by showing that it accounts for crucial distinctions in the behavior of nominalizations. The NP-DP split is challenged not only by competing frameworks or theories that argue, for instance, that NPs and
