DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SFUQNTAG/64/
 ">Lattice Walk Enumeration: Analytic\, algebraic and geometric aspects</a>
 \nby Marni Mishna (Simon Fraser University) as part of SFU NT-AG seminar\n
 \nLecture held in K-9509.\n\nAbstract\nThis talk will survey classificatio
 n of lattice path models via their generating functions.. A very classic o
 bject of combinatorics\, lattice walks withstand study from a variety of p
 erspectives. Even the simple task of classifying the two dimensional neare
 st neighbour walks restricted to the first quadrant has brought into play 
 a surprising diversity of techniques from algebra to analysis to geometry.
  We will consider walks under a few different lenses. We will see how latt
 ice walks can naturally guide the classification of functions into categor
 ies like algebraic\, D-finite\, differentiably algebraic and beyond.  Elli
 ptic curves and differential Galois theory play an important role.\n
