A Babylonian tower theorem for principal bundles over projective spaces

I. Biswas, I. Coanda, G. Trautmann

We generalise the variant of the Babylonian tower theorem for vector bundles on projective spaces proved by I. Coanda and G. Trautmann (2006) to the case of principal $G$ -bundles o…

Parabolic Raynaud bundles

Indranil Biswas, Georg Hein

Let X be an irreducible smooth projective curve defined over complex numbers, S= {p_1, p_2,...,p_n} \subset X$ a finite set of closed points and N > 1 a fixed integer. For any pair…

Stable real algebraic vector bundles over a Klein bottle

Usha N. Bhosle, Indranil Biswas

Let X be a geometrically connected smooth projective curve of genus one, defined over the field of real numbers, such that X does not have any real points. We classify the isomorph…

Connections on a parabolic principal bundle, II

Indranil Biswas

In \cite{Bi2} (Canad. Jour. Math. Vol. 58) we defined connections on a parabolic principal bundle. While connections on usual principal bundles are defined as splittings of the Ati…

Torelli theorem for moduli spaces of SL(r,C)-connections on a compact Riemann surface

Indranil Biswas, Vicente Muñoz

Let $X$ be any compact connected Riemann surface of genus $g \geq 3$ . For any $r \geq 2$ , let $M_{X}$ denote the moduli space of holomorphic $S L (r, C)$ -connections over $X$ . It is know…

Rational real algebraic models of topological surfaces

Indranil Biswas, Johannes Huisman

Comessatti proved that the set of real points of a rational real algebraic surface is either a nonorientable surface, or the two-sphere, or the torus. Conversely, it is easy to see…
