Title: The shifted sieve method on tournaments
Abstract: We construct a shifted version of the Tur\'an sieve method and apply it to some counting problems on tournaments. More precisely, we obtain upper bounds for the number of tournaments which contain a fixed number of $r$-cycles. We also consider an analogous question on $t$-partite tournaments. This is a joint work with Wentang Kuo, S\'avio Ribas and Kevin Zhou.
