Energy cascade in fluids: from convex integration to mixing
Alexey Cheskidov (Westlake University)
12:00 PM in 636 SEO
In the past couple of decades, mathematical fluid dynamics has
made significant strides with numerous constructions of solutions to fluid
equations that exhibit pathological or wild behaviors. These include the loss
of the energy balance, non-uniqueness, singularity formation, and dissipation
anomaly. Interesting from the mathematical point of view, providing
counterexamples to various well-posedness results in supercritical spaces,
such constructions are becoming more and more relevant from the physical
point of view as well. Indeed, a fundamental physical property of turbulent
flows is the existence of the energy cascade. Conjectured by Kolmogorov, it
has been observed both experimentally and numerically, but had been
difficult to produce analytically. In this talk I will overview new developments
in discovering not only pathological mathematically, but also physically
realistic solutions of fluid equations.

From Hamiltonian Systems to Drones: Geometric Insights into Control and Dynamics
Leonardo Colombo (Centre for Automation and Robotics CSIC-UPM)
2:00 PM in 636 SEO
Hamiltonian systems have long been a cornerstone of classical mechanics, providing a powerful framework to describe and analyze the motion of physical systems. But what happens when these mathematical structures take flight? In this talk, we will explore how the geometric principles of Hamiltonian mechanics play a crucial role in the modeling and control of modern aerial vehicles, including drones. From symplectic structures and variational principles to optimal control and real-world applications, we will uncover the elegant mathematical tools that bridge fundamental physics with cutting-edge drone technology. Whether you're interested in geometry, control theory, or just fascinated by the math behind autonomous systems, this talk will offer a compelling journey from theory to application in the skies.
