The 174th European Study Group with Industry will take place in the School of Management and Technology of Polytechnic of Porto (https://www.estg.ipp.pt/estg-en?set_language=en), from July 3rd to July 7th 2023. European Study Groups with Industry (ESGI) originated in Oxford in 1968, under the name of Oxford Study Groups with Industry. Study Groups are intensive week-long, team-based, problem-solvi
ng workshops that provide a unique opportunity for collaboration between mathematicians, scientists, and industrialists. A limited number of the challenges proposed by companies will be selected by the scientific committee to be tackled during ESGI174. On the first day of this event, academic participants will allocate themselves to a working group, each of which will work on one of the challenges along with the industrial partner during all the week. On the last day, each group will make a presentation of the main results obtained and suggest some directions for further work. A few weeks after the study group, a technical report describing the work of each group will be sent to the corresponding industrial partner. It will contain the main results achieved on the ESGI as well as other suggestions for further developments. More information on study groups and related aspects is available at the International Study Groups website, the Smith Institute and the European Consortium for Mathematics in Industry.
