On index divisors and monogenity of certain octic number fields defined by $x^8+ax^3+b$
UDC 511 For any octic number field $K$ generated by a root $\alpha$ of a monic irreducible trinomial $F(x)=x^8+ax^3+b \in \mathbb{Z}[x]$ and for every rational prime $p,$ we show when $p$ divides the index of $K.$  We also describe the prime power decomposition of the index...
