    An Extended Lachlan Splitting Theorem.Steffen Lempp & Sui Yuefei - 1996 - Annals of Pure and Applied Logic 79 (1):53-59.
    We show that the top of any diamond with bottom 0 in the r.e. degrees is also the top of a stack of n diamonds with bottom 0.

    The Cupping Theorem in R/M.Sui Yuefei & Zhang Zaiyue - 1999 - Journal of Symbolic Logic 64 (2):643-650.
    It will be proved that the Shoenfield cupping conjecture holds in R/M, the quotient of the recursively enumerable degrees modulo the cappable r.e. degrees. Namely, for any [a], [b] ∈ R/M such that [0] $\prec$ [b] $\prec$ [a] there exists [c] ∈ R/M such that [c] $\prec$ [a] and [a] = [b] ∨ [c].
