    Study Groups with Industry
    Dr. Eugene Kashdan, School of Mathematics and  Statistics, University College Dublin, Ireland

    European Study Groups with Industry (ESGI) are week-long problem-solving workshops, which provide a unique opportunity for interaction between mathematicians, statisticians, applied and computational scientists and industry. They bring together PhD Students, postdocs and professors to work intensively on real world problems. Originating in Oxford in 1968, ESGI have since been held several times a year across Europe and this format has been also successfully replicated in Australia and New Zealand. Companies in areas such as Environment, Finance, Electronics, and Renewable Energy have all previously benefited from this brainstorming, collaborative effort. The follow up to the ESGI usually includes scientific papers, grant applications and other forms of industry-academia collaboration. In my presentation, I will briefly talk about the history of the ESGI in Ireland, will discuss a number of industry problems successfully approached by the workshop participants and give some firsthand information on organization of such event.

    Twin primes in function fields and other problems
    Prof. Lior Bary, Tel-Aviv University

    Number theory concerns with arithmetic properties of the integer numbers; in particular, of prime numbers. In this area there is an abundance of ancient open problems. One of which is the problem about twin primes: are there infinitely many pairs of primes with difference two? If so, how many we have up to a large x?
    Hardy and Littlewood gave a conjectural formula for the ammount of twin primes.
    I will discuss this problem, and others, in the setting where one replaced the integers by the ring of polynomials over a finite field. I will present the resolution of it in one limit.

    Insurance for Service Failures
    Dr. Gal Zahavi, Department of Industrial Engineering, Technion

    Companies strive to maximize their profit using different methods e.g. Marketing, Organizational Change, Innovating products, Change of strategy and Revenue management (RM). The use of RM in profit maximization traditionally deals with optimizing pricing and delivery time of products and services. In this study we introduce a mechanism of revenue management based on allocating risk from the consumer to the service provider through a bundled insurance contract, that compensate the consumers in case of service default by the  service provider.
    We prove that by adding self-insurance mechanism, we improve profitability. Furthermore, additional profits can be earned by reducing the risk of damages for the consumers and finally we show that optimal service for maximum profitability doesn't imply risk free service.
