An outer billard map F is defined outside a closed convex curve Γ in the
following way. Let z be a point on the plane. Consider the supporting
line L(z) from z to Γ such that Γ lies on the rig...
The unbounded dead end depth property is not a group invariant
group invariant depth property
2015/8/26
The dead-end depth of an element g of a group with finite generating set A is the distance from g to the complement of the radius d(1,g) closed ball, in the word metric d. We exhibit a finitely presen...
The dead-end depth of an element g of a group G with generating set A is the distance from g to the complement of the radius d(1,g) closed ball, in the word metric d defined with respect to A. We exhi...

Products of Unbounded Normal Operators
Product of operators Normal hyponormal subnormal operators
2012/2/29
The present paper partly constitutes an "unbounded" follow-up of a paper by I. Kaplansky dealing with bounded products of normal operators. Results on the normality of unbounded products are also incl...
More on the Normality of the Unbounded Product of Two Normal Operators
Unbounded operators. Selfadjoint and normal operators. Operator products
2012/2/29
Let $A$ and $B$ be two -non necessarily bounded- normal operators. We give conditions making their product normal. This is a continuation of recently obtained results on this subject.
Online over time scheduling on unbounded p-batch machines to minimize the makespan: A survey
