The Hilbert schemes of points on surfaces with rational double point singularities [PDF]
We prove that the Hilbert scheme of points on a normal quasi-projective surface with at worst rational double point singularities is irreducible.

Asymptotically Hyperbolic Manifolds with Boundary Conjugate Points but no Interior Conjugate Points [PDF]
We construct non-trapping asymptotically hyperbolic manifolds with boundary conjugate points but no interior conjugate points.

Some Concepts of Modern Algebraic Geometry: Point, Ideal and Homomorphism [PDF]
Starting from classical algebraic geometry over the complex numbers (as it can be found for example in Griffiths and Harris it was the goal of these lectures to introduce some concepts of the modern point of view in algebraic geometry.

The Geometry of Fixed Point Varieties on Affine Flag Manifolds
Let $G$ be a semisimple, simply connected, algebraic group over an algebraically closed field $k$ with Lie algebra $\frak g$. We study the spaces of parahoric subalgebras of a given type containing a fixed nil-elliptic element of $\frak g\otimes k((\pi))$

Grassmannians of lines defined in the geometry of a pseudo-polarity [PDF]
The regular point-line geometry with respect to a pseudo-polarity is introduced. It is weaker than the underlying metric-projective geometry. The automorphism group of this geometry is determined. This geometry can be also expressed as the geometry of regular lines and planes.

Hilbert geometries with Riemannian points [PDF]
If a Hilbert geometry of twice differentiable boundary has two quadratic infinitesimal spheres, then the Hilbert geometry is a Cayley–Klein model of the hyperbolic geometry.

On the constellations of Weierstrass points [PDF]
We prove that the constellation of Weierstrass points characterizes the isomorphism-class of double covering of curves of genus large enough.

Five Definitions of Critical Point at Infinity [PDF]
This survey paper discusses five equivalent ways of defining a ``critical point at infinity'' for a complex polynomial of two variables.

Impartial Achievement Games on Convex Geometries [PDF]
We study a game where two players take turns selecting points of a convex geometry until the convex closure of the jointly selected points contains all the points of a given winning set. The winner of the game is the last player able to move. We develop a structure theory for these games and use it to determine the nim number for several classes of ...
