Title: Almost Steiner Designs
Speaker: Niranjan Balachandran, IIT Bombay
Abstract: We shall see a result of Ferber, Hod, Krivelevich, and Sudakov (2013) that shows that one can get almost Steiner designs in the following sense:
- The number of 'blocks' is (1+o(1))\frac{\binom{v}{t}}{\binom{k}{t}}
- Evert t-subset is contained in at least one and at most two blocks.
