A new 5-fold flop and derived equivalence

open access: yes, 2016
We describe a new example of a flop in 5-dimensions, due to Roland Abuaf, with the nice feature that the contracting loci on either side are not isomorphic. We prove that the two sides are derived equivalent.Comment: v1.

Birationally rigid Fano-Mori fibre spaces

open access: yesForum of Mathematics, Sigma
In this paper, we prove the birational rigidity of Fano-Mori fibre spaces $\pi \colon V\to S$ , every fibre of which is a Fano complete intersection of index 1 and codimension $k\geqslant 3$ in the projective space ${\mathbb P}^{M+k}$

Evaluation of filaggrin 2 expression in dogs with atopic dermatitis before and after oclacitinib maleate administration

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 453-461, August 2025.
Background – Canine atopic dermatitis (cAD) is a chronic, inflammatory, multifactorial and pruritic disease. The presence of skin barrier impairment (e.g. filaggrin alterations), along with abnormal immune responses, can negatively impact cutaneous barrier function.

Boundedness of slc degenerations of polarized log Calabi–Yau pairs

open access: yesForum of Mathematics, Sigma
Given a family of pairs over a smooth curve whose general fiber is a log Calabi–Yau pair in a fixed bounded family, suppose there exists a divisor on the family whose restriction on a general fiber is ample with bounded volume.

On Proper Polynomial Maps of $\mathbb{C}^2.$ [PDF]

open access: yes, 2009
Two proper polynomial maps $f_1, f_2 \colon \mathbb{C}^2 \longrightarrow \mathbb{C}^2$ are said to be \emph{equivalent} if there exist $\Phi_1, \Phi_2 \in \textrm{Aut}(\mathbb{C}^2)$ such that $f_2=\Phi_2 \circ f_1 \circ \Phi_1$.

Polar Cremona Transformations and Monodromy of Polynomials

open access: yes, 2007
Consider the gradient map associated to any non-constant homogeneous polynomial $f\in \C[x_0,...,x_n]$ of degree $d$, defined by \[\phi_f=grad(f): D(f)\to \CP^n, (x_0:...:x_n)\to (f_0(x):...:f_n(x))\] where $D(f)=\{x\in \CP^n; f(x)\neq 0\}$ is the ...

Varieties with vanishing holomorphic Euler characteristic II [PDF]

open access: yes, 2013
We continue our study on smooth complex projective varieties $X$ of maximal Albanese dimension and of general type satisfying $\chi(X, \omega_X)=0$. We formulate a conjectural characterization of such varieties and prove this conjecture when the Albanese

Invariants of Topological Relative Right Equivalences

open access: yes, 2012
The constancy of the Milnor number has several characterizations which were summarized by Greuel in 1986. This paper presents a study of these characterizations in the case of families of functions with isolated singularities defined on an analytic ...

Caustics of plane curves, their birationality and matrix projections

open access: yes, 2013
After recalling the notion of caustics of plane curves and basic equations, we first show the birationality of the caustic map for a general source point S in the plane.

On the birationality of the adjunction mapping of projective varieties [PDF]

open access: yes, 2011
Let $X$ be a smooth projective $n$-fold such that $q(X)=0$ and $L$ a globally generated, big line bundle on $X$ such that $h^0(K_X+(n-2)L) >0$. We give necessary and sufficient conditions for the adjoint systems $|K_X+kL|$ to be birational for $k \geq n ...
