 STRACT: Causal set theory is an approach to quantum gravity that\nproposes
  that spacetime is fundamentally discrete and the causal\nrelations among 
 the discrete elements play a prominent role in the\nphysics. Progress has 
 been made in recognizing and understanding how\nsome continuumlike feature
 s can emerge from causal sets at macroscopic\nscales\, i.e.\, when the num
 ber of elements is large. An important\nresult in this context is that a c
 ausal set is well approximated by a\ncontinuum spacetime if there is a num
 ber-volume correspondence between\nthe causal set and spacetime. \n\nThis 
 occurs when the number of elements within an arbitrary spacetime\nregion i
 s proportional to its volume. Such a correspondence is known\nto be best a
 chieved when the number of causal set elements is randomly\ndistributed ac
 cording to the Poisson distribution. I will discuss the\nPoisson distribut
 ion and the statistical fluctuations it induces in\nthe causal set-continu
 um correspondence\, highlighting why it is\nimportant and interesting. I w
 ill also discuss new tools and\ntechniques that facilitate such analyses.\
 n\nTHERE WILL BE A PRE-SEMINAR PRESENTING RELEVANT BACKGROUND AT THE\nBEGI
 NNING GRADUATE LEVEL STARTING AT 1PM\,
