Zero-cycles and cohomology on real algebraic varieties
, 1996 Let X be an algebraic variety over R, the field of real numbers. The interplay between the topology of the set of real points X(R) and the algebraic geometry of X has been the object of much study (Harnack, Weichold, Witt, Geyer, Artin/Verdier and Cox ...

Twisted ambidexterity in equivariant homotopy theory
Journal of Topology, Volume 19, Issue 2, June 2026.Abstract We develop the concept of twisted ambidexterity in a parametrized presentably symmetric monoidal ∞$\infty$‐category, which generalizes the notion of ambidexterity by Hopkins and Lurie and the Wirthmüller isomorphisms in equivariant stable homotopy theory, and is closely related to Costenoble–Waner duality.

Topology of algebraic curves: an approach via dessins d'enfants
, 2012 The book summarizes the state and new results on the topology of trigonal curves in geometrically ruled surfaces. Emphasis is placed upon various applications of the theory to related areas, most notably singularplane curves of small degree, elliptic ...

, 2000 This is the first attempt of a systematic study of real Enriques surfaces culminating in their classification up to deformation. Simple explicit topological invariants are elaborated for identifying the deformation classes of real Enriques surfaces. Some

The Equivariant Geometry of Nilpotent Orbits and Associated Varieties
, 2016 Nilpotent orbits are highly structured algebraic varieties lying at the interface of algebraic geometry, Lie theory, symplectic geometry, and geometric representation theory.

Viro theorem and topology of real and complex combinatorial hypersurfaces
, 2003 In this quite long and very well structured article the authors introduce the notion of combinatorial hypersurfaces, which are codimension 2 submanifolds of $\bbfC \bbfP^n$ invariant under complex conjugation whose real parts are codimension 1 ...

The Wu relations in real algebraic geometry
We construct and study relations between Chern classes and Galois cohomology classes in the Gal(C/R)-equivariant cohomology of real algebraic varieties with no real points. We give applications to the topology of their sets of complex points, and to sums
