In this note we list a number of open problems in the fields of numbertheory, combinatorics, and representation theory: algebraic functions withFermat property; power product expansion of the generating function for thepartition function; relation between the non-trivial Riemann zeros andeigenvalues of the transfer operator; functional equation related to normforms; two problems from geometric combinatorics; a problem on the moments ofthe Minkowski question mark function; a question in representation theory; aproblem on interpolating the moments of the Stern's diatomic sequence; anarithmetic properties of the binary composition function.
