Ju l 2 00 7 On some properties of σ ( N ) ∗ † Tomohiro

چکیده
We show asymptotic upper and lower bounds for the greatest common divisor of N and σ(N). We also show that there are infinitely many integers N with fairly large g.c.d. of N and σ(N).

3 1 Ju l 2 00 7 On the divisibility of odd perfect numbers by a high power of a prime ∗ † ‡
We study some divisibility properties of multiperfect numbers. Our main result is: if N = p1 1 · · · ps s q 2β1 1 · · · q 2βt t with β1, · · · , βt in some finite set S satisfies σ(N) = n d N , then N has a prime factor smaller than C, where C is an effective computable constant depending only on s, n, S.

Menger's basis property is a generalization of σ-comp-actness and admits an elegant combinatorial interpretation. We introduce a general combinatorial method to construct non σ-compact sets of reals with Menger's property. Special instances of these constructions give known counterexamples to conjectures of Menger and Hurewicz. We obtain the first explicit solution to the Hurewicz 1927 problem,...

The data for the production of the ψ ′ meson in pA collisions at 450 GeV at CERN-SPS (of the NA50-collaboration) [1] yields σ(ψ ′ N) ≈ 8 mb under the assumption that the ψ ′ is produced as a result of the space-time evolution of a point-like c¯ c pair which expands with time to the full size of the charmonium state. However, much higher values of σ(ψ ′ N) are not ruled out by the data. We show ...
متن کامل2 8 Ju n 20 09 LINEAR σ - ADDITIVITY AND SOME APPLICATIONS
We show that a large family of well-studied covering properties, which are not necessarily σ-additive, are preserved by countable increasing unions. Using this and simple forcing theoretic methods, we explain several phenomena, settle some problems, and construct topological groups with very strong combinatorial properties.

Strongly continuous one-parameter representations on a C *-algebra A and their extension to the multiplier algebra are investigated. We also give a proof of the Stone theorem on Hilbert C *-modules and look into some related problems.
