Abstract 
Quasirandomness
Spectral methods in graphs. When can we use the spectra? Large sets in finite fields. Quasirandomness is an important tool in additive combinatorics. We introduce the notation of quasirandomness to Cayley graphs. Then we use some basic Cheegertype inequalities to prove results on large subsets of finite fields.
