On linear sets on a projective line
Linear sets generalise the concept of subgeometries in a projective space. They have many applications in finite geometry. In this paper we address two problems for linear sets: the equivalence problem and the intersection problem. We consider linear sets as quotient geometries and determine the exact conditions for two linear sets to be equivalent. This is then used to determine in which cases...

15 صفحه اولLinear nonbinary covering codes and saturating sets in projective spaces
Let AR,q denote a family of covering codes, in which the covering radius R and the size q of the underlying Galois field are fixed, while the code length tends to infinity. The construction of families with small asymptotic covering densities is a classical problem in the area Covering Codes. In this paper, infinite sets of families AR,q, where R is fixed but q ranges over an infinite set of pr...
متن کاملOn Discrete Borel Spaces and Projective Sets
Let J denote the unit interval, S—IXI the unit square; Cj and Cs the class of all subsets of I and 6, respectively. By Cj X Cj is meant the or-algebra on S generated by rectangles with sides in C/. The purpose of this note is to prove the following theorem (which settles a problem of S. M. Ulam) and observe some of its consequences. Without explicit mention, the axiom of choice has been assumed...
متن کاملOn-line and Off-line POD assisted projective integral for non-linear problems: A case study with Burgers’ equation
The POD-assisted projective integration method based on the equation-free framework is presented in this paper. The method is essentially based on the slow manifold governing of given system. We have applied two variants which are the “on-line” and “off-line” methods for solving the one-dimensional viscous Bergers’ equation. For the on-line method, we have computed the slow manifold by extracti...
