TITLE Stable Rationality of del Pezzo Fibrations of Low Degree Over Projective Spaces
KIAS AUTHORS Krylov, Igor

ARCHIVE  
ABSTRACT The main aim of this article is to show that a very general three-dimensional del Pezzo fibration of degrees 1, 2, and 3 is not stably rational except for a del Pezzo fibration of degree 3 belonging to explicitly described two families. Higher-dimensional generalizations are also discussed and we prove that a very general del Pezzo fibration of degrees 1, 2, and 3 defined over the projective space is not stably rational provided that the anti-canonical divisor is not ample.
