Elyes Boughattas
Yanchevskiĭ had asked whether conic bundle surfaces over are unirational when is a finite field. We give a partial answer to his question by showing that for q…

The Grunwald problem and homogeneous spaces with non-solvable stabilisers
Elyes Boughattas, Danny Neftin
We give an affirmative answer to the Grunwald problem for new families of non-solvable finite groups G, away from the set of primes dividing |G|. Furthermore, we show that such G v…
