NTP2 conjecture for pseudo real closed and pseudo p-adically closed fields
NTP2 conjecture for pseudo real closed and pseudo p-adically closed fields
Recall that a field is pseudo real closed (PRC) if every absolutely irreducible variety defined over it that has a rational point in every real closure has a rational point in the field. A field is pseudo p-adically closed (PpC) if every absolutely irreducible variety defined over it that has a rational point in every p-adic closure has a rational point in the field. A field is bounded if, for every integer , it has only finitely many Galois extensions of degree .
PRC and PpC NTP2 conjecture. A PRC field is if and only if it is bounded. Similarly, a PpC field is if and only if it is bounded.
The unbounded PRC case is known to have , while the corresponding characterization for PRC and PpC fields remains conjectural.
