For a regular semisimple Higgs bundle with a smooth spectral curve, we prove that, over the \etale\ locus, the Atiyah class of the underlying bundle is induced by the Atiyah class…

Two characters on one punctured Riemann surface
Pradip Kumar
We develop an abstract framework for coupled period--realization of meromorphic --forms on punctured Riemann surfaces. A configuration datum gives the combinatorics and dete…
