In analytic number theory, the Dickman function or Dickman–de Bruijn function ρ is a special function used to estimate the proportion of smooth numbers up to a given bound. It was first studied by actuary Karl Dickman, who defined it in his only mathematical publication, which is not easily available, and later … See more The Dickman–de Bruijn function $${\displaystyle \rho (u)}$$ is a continuous function that satisfies the delay differential equation $${\displaystyle u\rho '(u)+\rho (u-1)=0\,}$$ with initial conditions See more The main purpose of the Dickman–de Bruijn function is to estimate the frequency of smooth numbers at a given size. This can be used to … See more Friedlander defines a two-dimensional analog $${\displaystyle \sigma (u,v)}$$ of $${\displaystyle \rho (u)}$$. This function is used to estimate … See more • Broadhurst, David (2010). "Dickman polylogarithms and their constants". arXiv:1004.0519 [math-ph]. • Soundararajan, Kannan (2012).

WebBAG genes have been found in yeasts, plants, and animals, and are believed to function as adapter proteins forming complexes with signaling molecules and molecular chaperones. In humans, a role for BAG proteins has been suggested in carcinogenesis, HIV infection, and Parkinson's disease.
