We introduce integration techniques allowing for the construction of  sc hemes which preserve the geometric structure and qualitative behavior of t he equation on the discrete level. Higher order extensions will be present ed\, following techniques based on decorated trees series inspired by sing ular stochastic PDEs via the theory of regularity structures.\n In the seco nd part\, we introduce a new approach for designing and analyzing schemes for some nonlinear and nonlocal integrable PDEs. This work is based upon r ecent theoretical breakthroughs on explicit formulas for nonlinear integra ble equations. It opens the way for studying the asymptotic behavior of th e solutions\, with applications to the soliton resolution conjecture\, and in wave turbulence theory.\n\n \n\nLocation : UdeM\, Pavillon André-Aisen stadt\, room 5183\n\nJoin Zoom Meeting\n\nhttps://umontreal.zoom.us/j/8952 8730384?pwd=IF10Cg8C0YfogaBlL6F1NboPaQvAaV.1\n\nMeeting ID: 895 2873 0384 \n\nPasscode: 077937\n DTSTART:20260116T190000Z DTEND:20260116T200000Z SUMMARY:Yvonne Alama Bronsard (MIT) URL:/qls/channels/event/yvonne-alama-bronsard-mit-3702 56 END:VEVENT END:VCALENDAR
