Séminaires : Phd Seminar - Séminaire des doctorant.e.s

Le séminaire des doctorant.e.s est l'occasion pour les doctorant.e.s de présenter des résultats et des problématiques dignes d'intérêt devant un public de non-spécialistes. L'ambiance y est informelle ; poser des questions naïves est encouragé, et les questions moins naïves sont bienvenues dans la mesure où elles n'entravent pas le bon déroulement de l'exposé.

Chaque jeudi à 18h, en alternance entre Jussieu et Sophie Germain.

The PhD seminar is an opportnuity for PhD students to present results and topics worthy of interest in front of a non-specialist audience. The mood is informal ; asking naive questions is highly encouraged and less naive questions are also welcomed, as long as they don't intefere with the smoothness of the talk.

Every Thursday at 6pm, alternating between Jussieu and Sophie Germain.

One of the classical problems in representation theory is to classify representations over an algebra upto isomorphisms. Since this is quite difficult in most cases, we restrict our attention to finite-dimensional representations. In this talk, we will see how we can use combinatorial tools like quivers to model finite-dimensional algebras and their representations. This will then allow us to provide an explicit description of all finite-dimensional representations and the irreducible maps between them over a class of algebras called 'string algebras'. These tools also provide us with suitable bounds on the ranks of such algebras.
