Parabolic SL(r)-opers
Indranil Biswas, Sorin Dumitrescu, Christian Pauly
We define SL(r)-opers in the set-up of vector bundles on curves with a parabolic structure over a divisor. Basic properties of these objects are investigated.
A Hodge theoretic projective structure on Riemann surfaces
Indranil Biswas, Elisabetta Colombo, Paola Frediani +1
Given any compact Riemann surface , there is a canonical meromorphic 2--form on , with pole of order two on the diagonal , constr…
Projective structures on Riemann surface and natural differential operators
Indranil Biswas, Sorin Dumitrescu
We investigate the holomorphic differential operators on a Riemann surface . This is done by endowing with a projective structure. Let be a theta characteristic…
Generalized B-Opers
Indranil Biswas, Laura P. Schaposnik, Mengxue Yang
Opers were introduced by Beilinson-Drinfeld [arXiv:math.AG/0501398]. In [J. Math. Pures Appl. 82 (2003), 1-42] a higher rank analog was considered, where the successive quotients o…
On vector bundles over hyperkähler twistor spaces
Indranil Biswas, Artour Tomberg
We study the holomorphic vector bundles E over the twistor space Tw(M) of a compact simply connected hyperkähler manifold . We give a characterization of the semistability condi…
Homogeneous Higgs and co-Higgs bundles on Hermitian symmetric spaces
Indranil Biswas, Steven Rayan
We define homogeneous principal Higgs and co-Higgs bundles over irreducible Hermitian symmetric spaces of compact type. We provide a classification for each type of object up to is…
