DESCRIPTION:CRM-ISM Probability Seminar\n\nTitle: Biconditioned Planar Maps
 \n\nAbstract: Consider all soccer balls having n^a edges obtained by gluin
 g n polygons\, and take one uniformly at random\; what does it look like w
 hen n is large? More formally\, what is the structure of random planar map
 s sampled at random according to face degree weights and which are conditi
 oned at the same time by their number of vertices\, edges and faces? We wi
 ll see in particular that typical distances in uniform maps with n^a edges
  and n faces is n^((2a-1)/4)\, which confirms a prediction of Fusy & Guitt
 er. Thanks to known bijections\, we will see that this amounts to establis
 hing scaling limits of nondecreasing integer-valued random walks condition
 ed by their terminal value at time n in various regimes\, which is of inde
 pendent interest. Joint work with Cyril Marzouk.\n\nLink: https://mcgill.z
