The aim of this note is to investigate the relation between two types of non-singular projective varieties of Picard rank 2, namely the Projective bundles over Projective spaces and certain Blow-up of Projective spaces.

Let $X$ be a smooth complex projective curve, and let $E$ be a vector bundle on $X$ which is not semistable. For a suitably chosen integer $r$, let $\text{Gr}(E)$ be the Grassmann bundle over $X$ that parametrizes the quotients of the fibers of $E$ o

In this article we prove a general result on a nef vector bundle $E$ on a projective manifold $X$ of dimension $n$ depending on the vector space $H^{n,n} (X, E). $ It is also shown that $H^{n,n} (X, E)=0$ for an indecomposable nef rank 2 vector bundl

Let G ‾ be the wonderful compactification of a simple affine algebraic group G of adjoint type defined over C . Let T ‾ ⊂ G ‾ be the closure of a maximal torus T ⊂ G . We prove that the group of all automorphisms of the variety T ‾ is the

We study the following question: Given a vector bundle on a projective variety $X$ such that the restriction of $E$ to every closed curve $C \,\subset\, X$ is ample, under what conditions $E$ is ample? We first consider the case of an abelian variety

We construct a degeneration of the moduli space of Hitchin pairs on smooth projective curves when the curve degenerates to an irreducible curve with a single node. The degeneration constructed here is analogous to the models constructed by Gieseker a

In this note we study the image of ℙ2 in Gr(2, ℂ4) given by tangent bundle of ℙ2. We show that there is component ℋ of the Hibert scheme of surfaces in Gr(2, ℂ4) with no point of it corresponds to a smooth surface.

Let G ‾ be the wonderful compactification of a simple affine algebraic group G defined over C such that its center is trivial and G ≠ PSL ( 2 , C ) . Take a maximal torus T ⊂ G , and denote by T ‾ its closure in G ‾ . We prove that T coinci
