Abstract

The paper studies the L2L^2-torsion of fibrations, focusing on cases that relax acyclicity and the determinant class condition. We prove the sum formula and the product formula for L2L^2-torsion in the extended abelian category. The desired formula for L2L^2-torsion of a simple fibration is obtained under the assumption that the fibers have zero Euler characteristic.
