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.

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

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 ...

Oscillation criteria for a class of partial functional-differential equations of higher order [PDF]

open access: yes, 2002
Higher order partial differential equations with functional arguments including hyperbolic equations and beam equations are studied. Sufficient conditions are derived for every solution of certain boundary value problems to be oscillatory in a ...

N-(1-Deoxy-α-d-tagatopyranos-1-yl)-N-methylaniline (“d-Tagatose-N-methylaniline”)

open access: yesMolbank, 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 ...

$$\theta $$ 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

A Historical Writing Apprenticeship for Adolescents: Integrating Disciplinary Learning With Cognitive Strategies [PDF]

open access: yes, 2016
This study explored the extent to which an 18â day history and writing curriculum intervention, taught over the course of one year, helped culturally and academically diverse adolescents achieve important disciplinary literacy learning in history ...

4d N $$ \mathcal{N} $$ = 1 from 6d D-type N $$ \mathcal{N} $$ = (1, 0)

open access: yesJournal of High Energy Physics, 2020
Compactifications of 6d N $$ \mathcal{N} $$ = (1, 0) SCFTs give rise to new 4d N $$ \mathcal{N} $$ = 1 SCFTs and shed light on interesting dualities between such theories.
