Together with an earlier work focused on d=11\, thi s puts AdS2 on the same geometric footing as its higher dimensional AdS co unterparts and provides powerful tools for the construction of many backgr ounds of physical interest. Examples include: black-hole near horizon geom etries\, holographic duals to superconformal quantum mechanics and duals t o conformal defects in higher dimensional CFTs.\n\nI will explain how thes e G-structure conditions may also be leveraged to construct solutions with extended supersymmetry and will provide some examples in this vein. Among st these my main focus will be on recently constructed solutions preservin g N=6 supersymmetry in massive type IIA and their dual description as well as a broad class in type IIB whose local form can be expressed in terms o f 2 holomorphic functions.\n LOCATION:https://researchseminars.org/talk/AnLy/53/ END:VEVENT END:VCALENDAR
