Bounds on the frequency of 1 in the Kolakoski word
Elizabeth J. Kupin, Eric S. Rowland
We use a method of Goulden and Jackson to bound freq_1(K), the limiting frequency of 1 in the Kolakoski word K. We prove that |freq_1(K) - 1/2| <= 17/762, assuming the limit exists…

Pattern avoidance in binary trees
Eric S. Rowland
This paper considers the enumeration of trees avoiding a contiguous pattern. We provide an algorithm for computing the generating function that counts n-leaf binary trees avoiding…
