Strongly maximal subgroups determined by elements in interstices
Mathematical Logic Quarterly, 2003AbstractContinuing the earlier research in [1] and [4] we work out a class of interstices in countable arithmetically saturated models of PA in which selective types are realized and a class of interstices in which 2‐indiscernible types are realized (and hence, there exist elements whose stabilizers are strongly maximal)

On the Number of Maximal Elements in a Partially Ordered Set
Canadian Mathematical Bulletin, 1987AbstractLet P be a partially ordered set. For an element x ∊ P, a subset C of P is called a cutset for x in P if every element of C is noncomparable to x and every maximal chain in P meets {x} ∪ C. The following result is established: if every element of P has a cutset having n or fewer elements, then P has at most 2n maximal elements. It follows that,

The “largest element first” heuristic for the maximization assignment problem
Computers & Operations Research, 1989The standard maximization assignment problem is as follows. Two sets I, J, are given, each with cardinality n. Assigning \(i\in I\) to \(j\in J\) incurs a score \(a_{ij}\). It is required to find a one-one mapping between I and J which has a maximal total score. The ``largest element first'' heuristic selects \((i_ 1,j_ 1)\in \arg\). \(\max_{(i,j)\in I\

Maximally Clustered Elements and Schubert Varieties
Annals of Combinatorics, 2007We introduce and study a class of “maximally clustered” elements for simply laced Coxeter groups. Such elements include as a special case the freely braided elements of Green and the author, which in turn constitute a superset of the iji-avoiding elements of Fan.
