Abstract

We first introduce the basic concepts of the brand new conic finance theory. Conic finance delivers a consistent two-price theory fundamentally modelling the acceptability of risks. Conic‎ pricing (or bid and ask pricing) of credit risk shows how counterparty credit risk when conservatively valued at the bid price results in larger CVA than would occur under risk neutral pricing. On the other hand when it comes to the debt valuation adjustment, since it is a liability, it must be priced at the ask. This mitigates and can even eliminate the DVA.‎ ‎

Title: Dynamic and Verifiable Hierarchical Secret Sharing

Abstract

In this work we provide a framework for dynamic secret sharing and present the first dynamic and verifiable hierarchical secret sharing scheme based on Birkhoff interpolation. Since the scheme is dynamic it allows, without reconstructing the message distributed, to add and remove shareholders, to renew shares, and to modify the conditions for accessing the message. Furthermore, each shareholder can verify its share received during these algorithms protecting itself against malicious dealers and shareholders. While these algorithms were already available for classical Lagrange interpolation based secret sharing, corresponding techniques for Birkhoff interpolation based schemes were missing. Note that Birkhoff interpolation is currently the only technique available that allows to construct hierarchical secret sharing schemes that are efficient and allow to provide shares of equal size for all shareholder in the hierarchy. Thus, our scheme is an important contribution to hierarchical secret sharing and to other techniques using this primitive, such as social secret sharing based cloud storage.

Title: Covering points with rotating polygons
Speaker: Carlos Seara (Universitat Politècnica de Catalunya)

Abstract

 We study the problem of rotating a simple polygon to contain the maximum number of elements from a given point set. We consider variations of this problem where the rotation center is a given point or lies on a line segment, a line, or a polygonal chain. This is a joint work with Carlos Alegría, David Orden, Leonidas Palios, and Jorge Urrutia.

Abstract

We present a unified framework to deal with threshold functions for the existence of solutions to systems of linear equations in random sets. This covers the study of several fundamental combinatorial families such as k-arithmetic progressions, k-sum-free sets, B_h(g)- sequences and Hilbert cubes of dimension k.

We show that there exists a threshold function for the property "A^m contains a non-trivial solution of Mx=0" where A is a random set. This threshold function depends on a parameter maximized over all subsystems, a notion previously introduced by Rödl and Rucinski. The talk will contain a formal definition of trivial solutions for any combinatorial structure, extending a previous definition by Ruzsa.

Joint work with Juanjo Rué Perna and Ana Zumalacárregui.

We would like to inform that we are organizing the fifth session of the Barcelona Computational, Cognitive and Systems Neuroscience (BARCCSYN 2016), which will be held at the Institut d’Estudis Catalans (Barcelona), on June 16 and 17, 2016.

BARCCSYN is about bringing together researchers from computational, systems and cognitive neuroscience. Our goal is to provide a forum for lively discussion and promote active collaboration between Barcelona-based research groups, especially between theorists and experimentalists.

Please note the following deadlines:

  • May 15: Deadline to present a poster or short communication.  
  • June 5: Deadline to register (or until all available seats are filled). 

Registration fee: 60 € (includes: documentation package, lunch tickets, and coffee breaks) 

You can find more information and register at:http://www.crm.cat/en/Activities/Curs_2015-2016/Pages/BARCCSYN-2016.aspx 
We hope that this information is of your interest and we hope to see you soon in Barcelona,
