Hello all, The next MaPSS talk of this semester will be at 17:00 on Mon 25th March in Carslaw 535. We are lucky enough to have Alice Belliere from the University of Namur give a talk this week! And as always, it’s a great opportunity to meet fellow postgrads, listen to an interesting talk, and of course get some free pizza! ************************************************************************************** Speaker: Alice Belliere Title: Desynchronization of the Kuramoto model using the collective coordinates Abstract: We witness in our surrounding that populations of humans or atoms or else animals are likely to synchronize their behaviour. We think for example about the neuronal synchronization in the brain. The aim of this synchronization is performing some actions like moving an arm. The action wouldn’t be possible if the neurons hadn’t synchronized such that the information can flow through the brain and reach their purpose. However, the synchronization of these systems is sometimes counterproductive. For example, the epileptic seizures are an over synchronization of the neurons and the brain can’t turn off by itself the message sent to the muscles. We will present the setup of a control in the Kuramoto model, model widely used for neuronal systems. That control, that we try to be as minimal as possible, should desynchronize the oscillators. Our approach is using the collective coordinates framework. ************************************************************************************** See you there!
