An introduction to Nichols Algebras
(Springer International Publishing, 2018)
Nichols algebras, Hopf algebras in braided categories with distinguishedproperties, were discovered several times. They appeared for the first time in the thesis of W. Nichols [72], aimed to construct new examples of Hopf ...
An introduction to resolution of singularities via the multiplicity
(Springer International Publishing, 2018)
In these notes, we study properties of the multiplicity at points of avariety X over a perfect field. We focus on properties that can be studiedusing ramification methods, such as discriminants and some generalizeddiscriminants ...

Metric geometry of partial isometries in a finite von Neumann algebra
(Elsevier, 2008-12)
We study the geometry of the set Ip = v ∈ M: v∗v = p of partial isometries of a finite von Neumann algebra M, with initial space p (p is a projection of the algebra). This set is a C∞ submanifold of M in the norm topology ...

A Lie algebra approach to Lie group time integration of constrained systems
(Springer International Publishing, 2016)
Lie group integrators preserve by construction the Lie group structure of a nonlinear configuration space. In multibody dynamics, they support a representation of (large) rotations in a Lie group setting that is free of ...
