Center node: "the capacity of some p olya string models"
  Abstract: We study random string-duplication systems, which we call P\'olya string models. These are motivated by DNA storage in living organisms, and certain random mutation processes that affect their genome. Unlike previous works that study the combinatorial capacity of string-duplication systems, or various string statistics, this work provides exact capacity or bounds on it, for several probabilistic models. In particular, we study the capacity of noisy string-duplication systems, including the tandem-duplication, end-duplication, and interspersed-duplication systems. Interesting connections are drawn between some systems and the signature of random permutations, as well as to the beta distribution common in population genetics.

Connected through hyperedge HE-1 (induced by source paper "zero error capacity of duplication channels"):
  with members:
    - "runlength limited sequences and shift correcting codes asymptotic analysis"
    - "bounds and constructions for multi symbol duplication error correcting codes"
    - "asymptotically optimal codes correcting fixed length duplication errors in dna storage systems"
    - "sharp analytical capacity upper bounds for sticky and related channels"
    - "on the capacity of channels with timing synchronization errors"
