We describe how such a series can be computed by finding an appropriate ordinary generating function and applying a certain transformation. We use this technique to find the generating function for the number of k-ary words avoiding any vincular pattern that has only ones, as well as words cyclically avoiding vincular patterns with only ones whose runs of ones between dashes are all of equal length.application/pdfen-USCopyright is held by the individual authors.Combinatorics; Combinatorics on words; Orthogonal polynomials; Pattern avoidanceMathematicsmathematicsThesis
