Báo cáo toán học: "A van der Waerden Variant" potx

... is the ﬁrst counterexample (under lexicographic ordering) to the variant van der Waerden property. We conjecture that for all S and k where the variant van der Waerden property fails, the ﬁrst ... because it exceeded a time limit. In the classical Van der Waerden Theorem, the case where S has two elements is not interesting. For the variant van der Waerden property, th...

... In the sequel, we denote S 2n the class of elevated Schröder paths of length 2n. We wish to use the area under Schröder paths to consider the combinatorial significance of the recurrence: f n+1 =6f n −f n−1 ,n≥2, ... combinatorial objects counted by the Schröder numbers, see [2, 4, 5, 6, 10, 11, 12, 13]. An elevated Schröder path is the path obtained from a Schröder path by adding a ris...
