 ">Order type of shifts of morphic words</a>\nby Yin Choi Cheng (CUNY Gradu
 ate Center) as part of Combinatorial and additive number theory (CANT 2022
 )\n\n\nAbstract\nThe shifts of an infinite word $W=a_0a_1\\cdots$ are the 
 words $W_i=a_ia_{i+1}\\cdots$. As a measure of the complexity of a word $W
 $\, we consider the order-type of the set of shifts\, ordered lexicographi
 cally. We will look at the order-type of shifts of morphic words over a fi
 nite alphabet that are not ultimately periodic. As a concrete example\, we
  give the explicit ordering among shifts of the Thue-Morse word. The order
  type of shifts of the Fibonacci word will be discussed. We then give spec
 ial consideration to uniform morphisms on 3 letters.\n
