Dense globally F-split type conjecture for varieties with int-amplified endomorphisms
Dense globally F-split type conjecture for varieties with int-amplified endomorphisms
Let be a normal projective variety over an algebraically closed field of characteristic zero. An endomorphism is int-amplified if there exists an ample Cartier divisor on such that is ample. The variety is of dense globally -split type if its reduction modulo is globally -split for infinitely many primes . Dense globally -split type conjecture. If admits an int-amplified endomorphism, then is of dense globally -split type. An affirmative answer to Schwede and Smith's question whether varieties of dense globally -split type are of Calabi–Yau type would imply the preceding Calabi–Yau type conjecture; this statement is open in the general setting.
