Nettet28. des. 2024 · I read several theorems regarding the classification of generic linear disjoint field extensions, however, I am interested in this special case, and was wondering whether there was more one could say in this situation. Nettet12. jan. 2024 · In the present paper, we give a simpler description of the obstruction group. It is also shown that if the étale algebra is a product of pairwise linearly disjoint field extensions, then the Hasse principle holds, and that if an embedding exists after an odd degree extension, then it also exists over the global field itself.
