Embedding more than 8 symplectic balls in
Sílvia Anjos, Jarek Kędra, Martin Pinsonnault
We prove that the space of symplectic embeddings of standard balls into the standard complex projective plane , normalized so that a line has symp…
Embeddings of symplectic balls into the complex projective plane
Sílvia Anjos, Jarek Kędra, Martin Pinsonnault
We investigate spaces of symplectic embeddings of balls into the complex projective plane. We prove that they are homotopy equivalent to explicitly described algebraic su…
European baskets in discrete-time continuous-binomial market models
Jarek Kędra, Assaf Libman, Victoria Steblovskaya
We consider a discrete-time incomplete multi-asset market model with continuous price jumps. For a wide class of contingent claims, including European basket call options, we compu…
Minimum Cost Super-Hedging in a Discrete Time Incomplete Multi-Asset Binomial Market
Jarek Kędra, Assaf Libman, Victoria Steblovskaya
We consider a multi-asset incomplete model of the financial market, where each of risky assets follows the binomial dynamics, and no assumptions are made on the joint dis…
On Lipschitz functions on groups equipped with conjugation-invariant norms
Jarek Kędra
We observe that a function on a group equipped with a bi-invariant word metric is Lipschitz if and only if it is a partial quasimorphism bounded on the generating set. We also show…
Uniform boundedness for algebraic groups and Lie groups
Jarek Kędra, Assaf Libman, Ben Martin
Let be a semisimple linear algebraic group over a field and let be the subgroup generated by the subgroups , where ranges over all the minimal -p…
Pricing multi-asset contingent claims in a multi-dimensional binomial market
Jarek Kędra, Assaf Libman, Victoria Steblovskaya
We consider an incomplete multi-asset binomial market model. We prove that for a wide class of contingent claims the extremal multi-step martingale measure is a power of the corres…
Fragmentation norm and relative quasimorphisms
Michael Brandenbursky, Jarek Kędra
We prove that manifolds with complicated enough fundamental group admit measure-preserving homeomorphisms which have positive stable fragmentation norm with respect to balls of bou…
The autonomous norm on is bounded
Michael Brandenbursky, Jarek Kędra
We prove that the autonomous norm on the group of compactly supported Hamiltonian diffeomorphisms of the standard is bounded.
On the cohomology of classifying spaces of groups of homeomorphisms
Jarek Kędra
Let M be a closed simply connected 2n-dimensional manifold. The present paper is concerned with the cohomology of classifying spaces of connected groups of homeomorphisms of M.
