On Hyperspatial Configurations
Presented by Harald GROPP
Type: Oral presentation
Track: Configurations
Content
A \lambda-configuration (v_k)_\lambda is a finite incidence structure of v points and v lines such that each line contains k points, through each point there are k lines, there are at most \lambda lines through two different points, and there are at most \lambda points in the intersection of two different lines.
A 1-configuration is just called configuration (or maybe combinatorial configuration).
A 2-configuration is also called spatial configuration.
For \lambda > 2 we choose the name hyperspatial configuration.
Modern research on spatial configurations started twenty years ago.
Here first results for \lambda = 3 (and \lambda = 4) will be presented, i.e. existence, enumeration, special properties, infinite series etc.
