Counting Lattice Paths
Counting lattice paths Maciej Dziemiańczuk A lattice path is a finite sequence of points p0, p1, . . . , pn in Z × Z, and a step of the path is the difference between two of its consecutive points, i.e., pi−pi−1. In this thesis, we consider lattice paths running between two fixed points and for which the set of allowable steps contains the vertical step (0,−1) and some number (possibly infinite...
متن کاملCounting Paths in Young’s Lattice
Young’s lattice is the lattice of partitions of integers, ordered by inclusion of diagrams. Standard Young tableaux can be represented as paths in Young’s lattice that go up by one square at each step, and more general paths in Young’s lattice correspond to more general kinds of tableaux. Using the theory of symmetric functions, in particular Pieri’s rule for multiplying a Schur function by a c...
متن کاملWhen Can We Lift the Coronavirus Pandemic Restrictions? Not Before Taking These Steps
When Can We Lift the Coronavirus Pandemic Restrictions? Not Before Taking These Steps. The American Enterprise Institute, a public policy think tank, recently released a report co-written by former U.S. Food and Drug Administration commissioner Scott Gottlieb that offers a four-phase “road map to reopening.” The first phase involves slowing the spread of new infections with physical distancing ...
متن کاملUnderdiagonal Lattice Paths with Unrestricted Steps
We wish to thank the anonymous referee whose comments helped us in improving the contents and readibility of our paper. 16 dominating singularity t = r of d(t). By a well-known result (see Bender 1], Theorem 2), it follows that d n;k p k (r))t n ]d(t): Since we already know the asymptotic value of t n ]d(t), we only have to compute p k (r) for every k 2 N. This is not diicult and we can nd a cl...
متن کاملCounting Nonintersecting Lattice Paths with Turns
We derive enumeration formulas for families of nonintersecting lattice paths with given starting and end points and a given total number of North-East turns. These formulas are important for the computation of Hilbert series for determinantal and pfaffian rings.
