[:is]Math Phys Seminar Titill: Holographic Complexity of Two-Dimensional Black Holes Fyrirlesari: Lukas Schneiderbauer, HÍ Staðsetning: VR-II 158Tími: Mánudaginn 29. apríl, kl. 10:00 Ágrip: Interest in holographic complexity arose when it was proposed as the dual quantity of the complexity of a quantum state in the context of AdS/CFT. However, it was realized that this quantity

[:is]Málstofa í stærðfræði Titill: Properties of solution trajectories for a metrically regular generalized equation Fyrirlesari: Iman Mehrabi Nezhad, HÍ Staðsetning: VR-II 258Tími: Fimmtudagur 11. apríl kl. 10.00 Ágrip: The presentation starts from a tangible example, analysis of electrical circuits. Using the circuit theory laws, and considering set-valued maps to model the i-v characteristics of semiconductors like diode, and transistor, a generalized equation is obtained.
