This paper begins with the observation that half of all graphs containing no induced path of length 3 are disconnected. We generalize this in several directions. First, we give necessary and sufficient conditions (in terms of generating functions) fo

An integer partition {λ1,λ2,...,λ v } is said to be graphical if there exists a graph with degree sequence 〈λ i 〉. We give some results corcerning the problem of deciding whether or not almost all partitions of even integer are non-graphical.

We consider the enumeration of the three-connected triangulations of the disk, with a reflective symmetry about a line. The asymptotic behavior is unlike that observed for rooted maps or for maps having rotational symmetry.

We classify self-avoiding polygons on the square lattice according to a concavity measure, m, where 2m is the difference between the number of steps in the polygon and the perimeter of the minimal rectangle bounding the polygon. We generate series ex

An abelian square is a string of length 2n where the last n symbols form a permutation of the first n symbols. In this note we count the number of abelian squares and give an asymptotic estimate of this quantity.

9-Aminocamptothecin (9-AC) is a topoisomerase I inhibitor with activity against xenografts from childhood solid tumors; however, clinical trials with this compound have been disappointing, resulting in discontinuation of further development. The obje
