Combinatorial study of morsifications of real univariate singularities
We study a broad class of morsifications of germs of univariate real analytic functions. We characterize the combinatorial types of the resulting Morse functions, via planar contact trees constructed from Newton-Puiseux roots of the polar curves of the ...

Exotic Spaltenstein Varieties [PDF]
We define a new family of algebraic varieties, called exotic Spaltenstein varieties. These generalise the notion of Spaltenstein varieties (which are the partial flag analogues to classical Springer fibres) to the case of exotic Springer fibres.

Finite sets of points in $\mathbb{P}^4$ with special projection properties
In this note we introduce the notion of $(b,d)$-geprofi sets and study their basic properties. These are sets of $bd$ points in $\mathbb{P}^4$ whose projection from a general point to a hyperplane is a full intersection, i.e., the intersection of a curve

On the topology of the moduli of tropical unramified $p$-covers
We study the topology of the moduli space of tropical unramified $\mathbb{Z}/p$-covers of tropical curves of genus $g \geq 2$ where $p$ is a prime number.

On the $PGL_2(q)$-orbits of lines of $PG(3,q)$ and binary quartic forms
We study the problem of classifying the lines of the projective $3$-space $PG(3,q)$ over a finite field $GF(q)$ into orbits of the group $G=PGL(2,q)$ of linear symmetries of the twisted cubic $C$.
