Outline of Final Research Achievements |
In this research project, we studied the extremal structures appeared in extremal combinatorics, and also discussed methods for this purpose. The two main results are as follows. We obtained an upper bound for the size of a set without a given "shape" in a vector space over a finite fields. We determined the extremal structure of the largest multiply intersecting families by using the corresponding spectral information.
