 Expansions in Complex Bases Beginning with a seminal paper of R\'enyi, expansions in noninteger real bases have been widely studied in the last forty years. They turned out to be relevant in various domains of mathematics, such as the theory of finite automata, number theory, fractals or dynamical systems. Several results were extended by Dar\'oczy and K\'atai for expansions in complex bases. We introduce an adaptation of the so-called greedy algorithm to the complex case, and we generalize one of their main theorems. Keywords:non-integer bases, greedy expansions, beta-expansionsCategories:11A67, 11A63, 11B85

 The Number of Non-Zero Digits of \$n!\$ Let \$b\$ be an integer with \$b>1\$. In this note, we prove that the number of non-zero digits in the base \$b\$ representation of \$n!\$ grows at least as fast as a constant, depending on \$b\$, times \$\log n\$. Category:11A63

 The Moments of the Sum-Of-Digits Function in Number Fields We consider the asymptotic behavior of the moments of the sum-of-digits function of canonical number systems in number fields. Using Delange's method we obtain the main term and smaller order terms which contain periodic fluctuations. Categories:11A63, 11N60
