Description

Risk modelling is an essential tool for the insurance industry.  Recent changes in regulation on a European level, the global reach of the European insurance industry and changing financial markets along with strong competition have created new challenges for the industry and for mathematicians.  A liberal regulatory regime allows insurance companies to develop comprehensive risk management systems through internal models.  Such models are complex and involve advanced mathematical methods. The integration of statistical data processing, development of actuarial models and management decisions is a challenging problem. 

The availability of big data and advanced methods of machine learning is a new frontier for the insurance industry.  Applications range from detecting fraudulent practices, segmentation of customers, advanced pricing models to assisted financial decisions.  Fundamental mathematical questions of reliability and replicability of such applications must be addressed not only in insurance but in all applications of machine learning. 

The speakers will discuss modelling challenges and more fundamental questions of machine learning applications.  There has been a rising trend in weather-related claims stretching the capacity of (re)insurance to its limits.  Complex mathematical models to adjust for trends and assist with pricing in non-life insurance is yet another challenge for mathematical modelling.  Some new advances in this respect will be presented.

Description

 

Blockchain is an innovative technology that has the potential to transform many areas such as finance, logistics, and connected object management. It provides a means for exchanging or storing information secured by cryptography without the need of a centralized trusted authority. 

The lack of a global trusted third party is bypassed by relying on a publicly readable and writeable blockchain, a data structure in which all transactions are gradually added by creating cryptographically linked blocks.

Initially introduced in 2008, the Bitcoin cryptocurrency system offers its users the possibility to transfer funds (in Bitcoins) securely without a banking authority. Since then, new blockchain models have been introduced: blockchain technology is still in the development phase and an open field of research. To ensure the viability of candidate improvement solutions, mathematical models and analyses tackling different blockchain aspects (consensus, forks, block creation or block spreading time, etc.) have been proposed during the last decades. 

This mini-symposium aims to bring together researchers active on blockchain analysis and allow the interaction between different expertises: Markov chain, game theory, fluid limits and different types of stochastic processes. It also aims to gather mathematicians analyzing blockchains through a theoretical approach to those applying numerical techniques, and thus it will encourage new collaborations.
