Over-Luminous Type Ia Supernovae and Standard Candle Cosmology
Abhinandan Ravi, T. R. Govindarajan, Surajit Kalita
Type Ia supernovae (SNe\,Ia) serve as crucial cosmological distance indicators because of their empirical consistency in peak luminosity and characteristic light curve decline rate…
Magnetic field measurements on the mini-ICAL detector using Hall probes
Honey, B. Satyanarayana, R. Shinde +8
The magnetised 51 kton Iron Calorimeter (ICAL) detector proposed to be built at INO is designed with a focus on detecting 1-20 GeV muons. The magnetic field will enable the measure…
Chern-Simons classes of flat connections on supermanifolds
JN Iyer, Un Iyer
In this note we define Chern-Simons classes of a superconnection on a complex supervector bundle such that is flat and preserves the grading, and is an odd endomo…
Regulators of canonical extensions are torsion: the smooth divisor case
Jaya N. Iyer, Carlos T. Simpson
In this paper, we prove a generalization of Reznikov's theorem which says that the Chern-Simons classes and in particular the Deligne Chern classes (in degrees ) are torsion, o…
The Chern character of a parabolic bundle, and a parabolic Reznikov theorem in the case of finite order at infinity
Jaya N. Iyer, Carlos T. Simpson
In this paper, we obtain an explicit formula for the Chern character of a locally abelian parabolic bundle in terms of its constituent bundles. Several features and variants of par…
A relation between the parabolic Chern characters of the de Rham bundles
Jaya N. Iyer, Carlos T. Simpson
In this paper, we consider the weight de Rham--Gauss--Manin bundles on a smooth variety arising from a smooth projective morphism $f:X\_U\lrar U$ for . We associate to…
