SUMMARY:Random Regular Graphs: Generation and Cover Time
DESCRIPTION:Speaker: Mohit Garg\nTata Institute of Fundamental Research\nSc
 hool of Technology and Computer Science\nHomi Bhabha Road\n\nAbstract: \nA
  graph is $r$-regular if all its vertices have the same degree $r$. A rand
 om $r$-regular graph with $n$ vertices is a graph sampled uniformly at ran
 dom from the set of all $r$-regular graphs on $n$ vertices. There are vari
 ous sampling methods for this. In this talk we look at one of them: The Co
 nfiguration Model. We then look at the cover time of a random walk on such
  a graph\, which roughly speaking\, is the time taken (in expectation) by 
 the walk to visit all the vertices. This cover time calculation\, due to C
 olin Cooper and Alan Frieze\, uses generating function technique and resul
 ts from complex analysis\, which we illustrate in this talk.\n\n(Key words
