Multidegrees of Tame automorphisms with one prime number

Jiantao Li, Xiankun Du

Let $3 \leq d_{1} \leq d_{2} \leq d_{3}$ be integers. We show the following results: (1) If $d_{2}$ is a prime number and $\frac{d _{1}}{g c d ( d _{1} , d _{3} )} \neq = 2$ , then $(d_{1}, d_{2}, d_{3})$ is a multidegr…
