Torsion of extended Chern-Simons classes for canonical extensions of flat bundles
Jaya NN Iyer, Carlos Simpson
Let be a smooth complex projective variety and a divisor with simple normal crossings. Consider Deligne's canonical extension of a fl…

Regulators of canonical extensions are torsion:the case of two transversally intersecting smooth divisors
Jaya NN Iyer, Carlos Simpson
This note extends the main result of \cite{IS} 2007 --- torsion of the extended Chern--Simons (regulator) classes of the Deligne canonical extension of a flat bundle with unipotent…
