Bulk Physics, Algebras and All That: Part One

 A set of notes, titled Bulk Physics, Algebras and All That, which I have been writing from a couple of weeks has been almost completed. This set of notes is split into three parts -- part one, where bulk reconstruction and aspects of subregion duality are discussed; part two, where most of the focus is on QES and things like their relation to the information problem in AdS/CFT is presented; and part three, where some of the recent things I learnt about JT gravity and SYK model are discussed. Part three still needs some work, but as of now part one has been completed. There are some omissions and refinements to take into account in future revisions, due to which for now, here is part one.
