Most Latin Squares Have Many Subsquares
A k_n Latin rectangle is a k_n matrix of entries from [1, 2, ..., n] such that no symbol occurs twice in any row or column. An intercalate is a 2_2 Latin subrectangle. Let N(R) be the number of intercalates in R, a randomly chosen k_n Latin rectangle. We obtain a number of results about the distribution of N(R) including its asymptotic expectation and a bound on the probability that N(R)=0. For...
متن کاملCharacterizing Projective Spaces for Varieties with at Most Quotient Singularities
We generalize the well-known numerical criterion for projective spaces by Cho, Miyaoka and Shepherd-Barron to varieties with at worst quotient singularities. Let X be a normal projective variety of dimension n ≥ 3 with at most quotient singularities. Our result asserts that if C · (−KX) ≥ n + 1 for every curve C ⊂ X, then X ∼= P .
متن کاملGroups with Finitely Many Countable Models
We construct Abelian group with an extra structure whose first order theory has finitely many but more than one countable model.
متن کاملWhy have total cholesterol levels declined in most developed countries?
BACKGROUND Our paper addresses three major public health issues: cholesterol, statins and policies to prevent cardiovascular disease. DISCUSSION Total cholesterol levels in whole populations have fallen substantially in the USA, UK and most other developed countries. This has greatly contributed to decreases in cardiovascular disease deaths. The evidence identifying diet as the major contribu...
متن کاملEmbeddedness of Minimal Surfaces with Total Boundary Curvature at Most
This paper proves that classical minimal surfaces of arbitrary topological type with total boundary curvature at most 4 must be smoothly embedded. Related results are proved for varifolds and for soap lm surfaces. In a celebrated paper N3] of 1973, Nitsche proved that if ? is an analytic simple closed curve in R 3 with total curvature at most 4, then ? bounds exactly one minimal disk M. Further...
