Let $\mathcal{ K}_n$ be the so-called wild Kronecker quiver, i.e., a quiver with one source and one sink and $n\geq 3$ arrows from the source to the sink. The following problems will be studied for an arbitrary regular component $\mathcal{ C}$ of the Auslander-Reiten quiver: (1) What is the relationship between dimension vectors and quasi-lengths of the indecomposable regular representations in $\mathcal{ C}$? (2) For a given natural number $d$, is there an upper bound of the number of indecomposable representations in $\mathcal{ C}$ with the same length $d$? (3) When do the sets of the dimension vectors of indecomposable representations in different regular components coincide?
