      Characterizations, length-biasing, and infinite divisibility 

      Pakes, A. G.; Sapatinas, Theofanis; Fosam, E. B. (1996)
      Suppose L(X) is the law of a positive random variable X, and Z is positive and independent of X. Admissible solution pairs (L(X),L(Z)) are sought for the in-law equation X̂ ≅ X o Z, where L(X̂) is a weighted law constructed ...

      Some new approaches to infinite divisibility 

      Sapatinas, Theofanis; Shanbhag, D. N.; Gupta, A. K. (2011)
      Using an approach based, amongst other things, on Proposition 1 of Kaluza (1928), Goldie (1967) and, using a different approach based especially on zeros of polynomials, Steutel (1967) have proved that each nondegenerate ...
