SUMMARY:Characterizing Transcendence in Combinatorics
LOCATION: Zoom Link [password: The 20th Catalan number\, alias (40)!/(20!*21!)\, ali
 as 6564120420 ]
DESCRIPTION:<p>The problem of understanding the structure of transcendental objects has
  fascinated mathematicians for well over a century. Combinatorics provides 
 an intuitive framework to study power series. A combinatorial family is ass
 ociated to a power series in R[[t]] via its enumerative generating function
  wherein the number of objects of size n is the coefficient of t^n. Twentie
 th century combinatorics and theoretical computer science provided characte
 rizations of classes with rational and algebraic generating functions. Find
 ing natural extensions of these correspondences has been a motivating goal 
 of enumerative combinatorics for several decades. This talk will focus on t
 wo well studied classes of transcendental functions: the differentiably fin
 ite and differentially algebraic.</p>
