Variations on Nagata’s Conjecture
Here we discuss some variations of Nagata’s conjecture on linear systems of plane curves. The most relevant concerns non-effectivity (hence nefness) of certain rays, which we call good rays, in the Mori cone of the blowup Xn of the plane at n ≥ 10 general points. Nagata’s original result was the existence of a good ray for Xn with n ≥ 16 a square number. Using degenerations, we give examples of...
متن کاملVariations on the Sensitivity Conjecture
We present a selection of known as well as new variants of the Sensitivity Conjecture and point out some weaker versions that are also open.
متن کاملSome variations on the telescope conjecture
This paper presents some speculations about alternatives to the recently disproved telescope conjecture in stable homotopy theory. It includes a brief introduction to the parametrized Adams spectral sequence, the main technical tool used to disprove it. An example supporting the new conjectures is described.
متن کاملVariations on a Conjecture of Halperin
Halperin has conjectured that the Serre spectral sequence of any fibration that has fibre space a certain kind of elliptic space should collapse at the E2-term. In this paper we obtain an equivalent phrasing of this conjecture, in terms of formality relations between base and total spaces in such a fibration (Theorem 3.4). Also, we obtain results on relations between various numerical invariant...
متن کاملSome Variations on the Dedekind Conjecture
In this note we prove a group theoretic statement about expressing certain characters of a finite solvable group as a sum of monomial characters. This is used to prove holomorphy of certain products of Artin L-functions which can be thought of as a variant of the Dedekind Conjecture. This variant is then used to improve, in the solvable case, a certain inequality due to R. Foote and K. Murty wh...
