After motivating the pr oblem and looking a little at the Ising case for the sake of comparison\, we will discuss our main results and time permitting\, some proof techniqu es. Our results include convergence of the pressure per particle for a rat her general class of weights\, no phase transition for infinite variance w eights — the system is always ordered for any positive temperature\, for f inite-variance weights — a proof of the first order phase transition at th e critical temperature under a quite general condition\, and for the speci al case of Pareto weights with power law exponent $\tau$ — a `phase transi tion smoothening' — the phase transition is first order when $\tau \geq 4$ \, while when $\tau \in (3\,4)$\, it is first order when $\tau \in (\tau(q )\,4)\, while it is second order for $\tau \in (3\, \tau(q)]$. We end with a discussion on future extensions and open problems. This is based on joi nt work with Cristian Giardinà (Modena)\, Claudio Giberti (Modena)\, Remco van der Hofstad (Eindhoven) and Guido Janssen (Eindhoven).\n DTSTART:20251127T163000Z DTEND:20251127T173000Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Neeladri Maitra (UIUC) URL:/channels/channels/event/neeladri-maitra-uiuc-3688 01 END:VEVENT END:VCALENDAR
