Two divisors of ( n 2 + 1 ) / 2 summing up to n + 1 par Mohamed
In this short note, we give an affirmative answer to a question of Ayad from [1]. 1. Main result In [1], Mohamed Ayad asked to prove that there does not exist an odd prime p and two positive divisors d1 and d2 of (p2 +1)/2 such that d1 +d2 = p+ 1. In this note, we prove a bit more, namely: Theorem 1.1. There does not exist an odd integer n > 1 and two positive divisors d1 and d2 of (n2 + 1)/2 s...
متن کاملScalar mesons and δ 0 − δ 2 at KLOE
The KLOE measurements of φ radiative decays and of the ratio Γ(K S → π + π − (γ))/Γ(K S → π 0 π 0) are discussed. The first measurement aims at understanding the real nature of the scalar mesons a 0 and f 0 , whose possible compositions are q ¯ q, qq ¯ q ¯ q, or K ¯ K molecule. The second measurement is related to the estimate of the phase shift difference δ 0 − δ 2. Previous measurements were ...

متن کاملDirichlet Heat Kernel Estimates for Δ +δ
For d ≥ 1 and 0 < β < α < 2, consider a family of pseudo differential operators {Δ + aΔ; a ∈ [0,1]} on R that evolves continuously from Δ to Δ + Δ. It gives arise to a family of Lévy processes {X, a ∈ [0,1]} on R, where each X is the independent sum of a symmetric α-stable process and a symmetric β-stable process with weight a. For any C open set D ⊂R, we establish explicit sharp two-sided esti...
متن کاملDetecting Omnivory with Δ Δ 15 N
is no unambiguous evidence that plumicolous feather mites chew holes in feathers; such damage is usually caused by feather lice. Also, it has been reported that feather mites of the great-spotted woodpecker (Dryobates major) and the hoopoe (Upupa epops) avoid white spots on the feathers and instead aggregate on melanized areas 5. Thus, as we stressed in our review 3 , extrapolating from lice to...
