Abstract
Let be a global field and be an odd prime number. We give a necessary and sufficient condition for the Hasse norm principle for separable field extensions , i.e. the determination of the Shafarevich-Tate group of the norm one tori of , with or when the Galois group of the Galois closure of is the Heisenberg group of order , i.e. the extraspecial group of order with exponent . As a consequence, we get the Tamagawa number , or via Ono's formula .
