Janelidze, L. Márki and W. Tholen in 2002, generalizes that of abelian category, and captures the homological properties that the categories of groups, associative algebras, Lie algebras and cocommutative Hopf algebras over a field have in common. Internal structures behave surprisingly well in semi-abelian categories. For example, any internal reflexive graph admits at most one internal category structure, and the categories of internal categories and internal groupoids are isomorphic. Moreover, the category of internal groupoids is equivalent to the category of internal crossed modules. The notion of internal crossed module in any semi-abelian category was introduced by G. Janelidze in 2003, and recovers in particular the classical notion of crossed module of groups. The fact that the category of internal groupoids in a semi-abelian category is itself semi-abelian implies that also the category of internal n-fold groupoids is well-behaved.<br>\r\n <br>\r\nIn this talk, I will prove that the full subcategory of internal n-groupoids in a semi-abelian category is a Birkhoff subcategory of the category of internal n-fold groupoids, and provide a simple description of the corresponding reflection for n=2.

Motivated by recent results on the higher moments of the SHE in two dimensions at $L^{2}$-criticality, a natural question is whether the higher moments of the SHE in high dimensions also converge at the $L^{2}$-critical point. Our main result gives a negative answer: in high dimensions, the higher moments diverge when the coupling constant belongs to a nontrivial right-closed interval whose upper endpoint is the $L^{2}$-critical point. In particular, we obtain a sharp bound for the critical coupling constant at which the corresponding limiting higher moment undergoes a phase transition.

In contrast to zero-sum games—which do not always capture conflict, even between two players—harmonic games may exhibit highly non-convex equilibrium configurations. In particular, if the game’s ambient dimension is odd, we show that the set of totally mixed Nash equilibria is a (typically non-convex) real algebraic variety of dimension at least one, which extends all the way to the boundary of the game’s strategy space. Despite the difficulties incurred by this complicated equilibrium structure, we provide an extrapolation-based variant of “follow-the-regularized-leader” (FTRL) which converges to Nash equilibrium with order-optimal regret guarantees: O(1) in self-play, and O( sqrt(T) ) against arbitrary play.<br>\r\n<br>\r\n<br>\r\n<strong>Biography</strong><br>\r\nDavide Legacci is a PhD candidate in Computer Science at Université Grenoble Alpes, CNRS and Inria, within the GHOST team, supervised by Panayotis Mertikopoulos and Bary S.

Solar and wind energy harvesting combined with chemical energy storage in batteries or fuels, such as hydrogen, are essential processes, that need to be improved in terms of efficiency, long-term stability, scalability and sustainability. Although significant progress has been made, many proposed photo- or electrochemical devices show satisfying short-term efficiencies in the laboratory but are too cost-intensive, too unstable and/or not sustainable enough for large-scale applications [1][2]. This is often the case, because they rely on rare materials and/or they are not fabricated using scalable processes. From a material science point of view, key areas to improve dynamic processes include, of course, the bulk properties of the active materials themselves, as well as the interfaces between the active materials and the electrolyte [3]. <br>\r\nIn this contribution concepts are presented how to improve the function of active materials in photo- or electrochemical energy applications by materials and interface design while respecting sustainability criteria. Our strategies include morphology control by scalable synthesis procedures and chemical modifications using earth-abundant and sustainable additives. These approaches are showcased in two application areas: photocatalysis for solar water-splitting and post-lithium-ion batteries. In both cases vanadium-based chemistries and low energy hydrothermal synthesis processes are used to produce devices with improved function [4,5].<br>\r\n[1] A. Vilanova, P. Dias, T. Lopes and A.

Historically, research has primarily focused on predicting the onset of buckling—that is, the loss of the original configuration under excessive loading—rather than on understanding how structures evolve in the post-buckling regime. Recently, however, the study of buckling has experienced a renaissance, with post-buckling mechanical responses increasingly exploited to achieve new functionalities, for example enhancing fracture resistance in stretchable electronics and flexible displays.<br>\r\n<br>\r\nWhile most existing studies consider elastically deforming systems whose behaviour arises primarily from geometric nonlinearities, this talk presents examples in which geometric effects are coupled with nonlinear constitutive responses, giving rise to new post-buckling mechanisms. First, we investigate the buckling of hard, perforated (“holey”) structures that exhibit auxetic behaviour but, unlike their purely elastic counterparts, undergo post-buckling softening. The resulting negative stiffness is captured using a pseudo-plastic constitutive model that describes nonlinearities emerging from the structural microarchitecture.<br>\r\n<br>\r\nWe then apply a similar framework to examine the buckling of beverage cans largely filled with liquid under axial compression. Whereas empty cylindrical shells typically develop periodic buckling patterns that break both axial and circumferential symmetry, liquid-filled cylinders buckle axisymmetrically. The resulting ring-shaped buckles are localized and emerge sequentially, progressively covering the can surface. We show that this behaviour arises from nonlinear, spatially anisotropic hoop stresses that soften and subsequently re-stiffen during compression.<br>\r\n<br>\r\n<strong>Biography: </strong>Draga Pihler-Puzovic is a Reader in the Department of Physics and Astronomy at the University of Manchester and a core member of the Manchester Centre for Nonlinear Dynamics.
