An explicit structure-preserving filtered Lie splitting scheme for the original Zakharov system with low regularity error estimates in all dimensions
In this talk, we present error estimates for a fully discrete filtered Lie splitting scheme applied directly to the Zakharov system, whose solutions may exhibit very low regularity in arbitrary dimensions. Quite remarkably, we observe that the scheme exhibits an \emph{approximately structure-preserving} behavior even in the fully discrete setting. Our analysis relies on multilinear estimates developed within the framework of discrete Bourgain spaces. In particular, we prove that if the exact solution $(E,z,z_t)\in H^{s_c+r+1/2}\times H^{s_c+r}\times H^{s_c+r-1}$, then the numerical error measured in $H^{r+1/2}\times H^{r}\times H^{r-1}$ is of order $\mathcal{O}(\tau^{s_c/2}+N^{-s_c})$ for $s_c\in(0,2]$, where $r=\max(0, d/2-1)$ and $N$ denotes the number of spatial grid points. To the best of our knowledge, this is the first explicit error estimate for a numerical method designed directly for the original Zakharov system, without introducing auxiliary variables or reformulations. Such reformulations typically break the geometric structure of the system, whereas our approach approximately preserves it by working with the system in its original form. Finally, numerical experiments are provided to validate and illustrate our theoretical results.

Inner radius estimates and rigidity for a Finsler measure space with boundary
In this lecture, we give an estimate of the upper bound of the inner radius for a complete Finsler measure space $(M,F,d\mu)$ of weighted Ricci curvature bounded from below, in terms of the $d\mu$-mean curvature bound of the boundary. We also prove the rigidity result that when the boundary is compact, the upper bound is achieved if and only if $M$ is isometric to a forward Finsler geodesic ball of vanishing radical flag curvature.

Veni, Sensi, Vici: Touch, on the Robot Physical Intelligence
The sense of touch is arguably the most fundamental yet taken-for-granted sensing modality in human physical interactions. It enriches our perception, enabling dexterous manipulation and acting as a safety net. Likewise, robots have been increasingly required to work outside their historical cages and manipulate a growing range of objects. Achieving human-like dexterity in robots is important for their successful blending into our human environments. This requires robots to move beyond basic rigid-object grasping and perform more complex manipulation tasks. In this talk, we will discuss how robots can build an action hierarchy with the sense of touch to acquire and internalise various manipulation skills safely and dexterously, paving the way for physical intelligence for robots.
