The block structure spaces of real projective spaces and orthogonal calculus of functors

open access: yes, 2006
Given a compact manifold X, the set of simple manifold structures on X x \Delta^k relative to the boundary can be viewed as the k-th homotopy group of a space \S^s (X). This space is called the block structure space of X.

open access: yesarXiv, 2010
We determine the Batalin-Vilkovisky algebra structure of the integral loop homology of quaternionic projective spaces and octonionic projective plane.

Tetrahedral quartics in Projective Space [PDF]

open access: yesarXiv, 2012
We study tetrahedral quartics in projective space. We address their projective geometry, Neron-Severi lattice and automorphism group.

Monomial Transformations of the Projective Space [PDF]

open access: yes, 2014
We prove that, over any field, the dimension of the indeterminacy locus of a rational transformation $f$ of $P^n$ which is defined by monomials of the same degree $d$ with no common factors is at least $(n-2)/2$, provided that the degree of $f$ as a map is not divisible by $d$. This implies upper bounds on the multidegree of $f$.

Symbol calculus on a projective space [PDF]

open access: yesarXiv, 2013
In this article, we introduce symbol calculus on a projective scheme. Using holomorphic Poisson structures, we construct deformations of ring structures for structure sheaves on projective spaces.

Smooth blow up structures on projective bundles [PDF]

open access: yesarXiv
Assuming Hartshorne's conjecture on complete intersections, we classify projective bundles over projective spaces which has a smooth blow up structure over another projective space. Under some assumptions, we also classify projective bundles over projective spaces which has a smooth blow up structure over some arbitrary smooth projective variety, not ...
