DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/70/">Wa
 rped Flux Compactifications: Effective Potentials and Numerical Geometry</
 a>\nby Severin Lüst (Paris\, LPTHE) as part of AnLy Strings and Fields on
 line seminars\n\n\nAbstract\nIn this talk\, I will discuss two complementa
 ry approaches to warping in Type IIB flux compactifications. Such compacti
 fications are a central ingredient in many string theory de Sitter constru
 ctions. First\, I will describe a systematic derivation of warping correct
 ions to the effective scalar potential and their implications for F-term d
 e Sitter uplifting\, highlighting the challenges for control in KKLT and t
 he LVS. I will then present numerical constructions of warped Calabi–Yau
  backgrounds using physics-informed neural networks to approximate Ricci-f
 lat metrics\, harmonic fluxes\, and warp factors. Applications to the Dwor
 k family of quintics provide a concrete setting to explore warped throats 
 and the singular bulk problem.\n
