DESCRIPTION:Speaker: Eng-Jon Ong (Queen Mary University of London)\n\nTit
 le: Discrete spectrum in S-adic substitution dynamical systems via the b
 alanced pair algorithm\n\nAbstract: Substitutions and S-adic dynamical s
 ystems are a natural framework for generating and studying infinite symb
 olic sequences via the iterative application of substitution rules. For 
 two-letter symbolic dynamical systems arising from a single Pisot substi
 tution\, it is known that the associated dynamical system has purely dis
 crete spectrum. In this talk\, we extend this result to a class of S-adi
 c systems generated by a finite set of substitutions. Our approach is ba
 sed on the Balanced Pair Algorithm\, and we prove that this algorithm te
 rminates for two-symbol S-adic systems\, a key step in establishing pure
  discrete spectrum in this setting. We also establish the existence of a
 n asymptotic expansion rate for growing words in S-adic systems.\n\nRoom
