Explore advanced topics in string field theory and string perturbation theory through this comprehensive conference featuring leading researchers in theoretical physics. Delve into cutting-edge developments including worldline approaches to infinite field theories, classical solutions in string field theory, and unconventional D-branes on T^4. Examine closed string amplitudes from single-valued correlation functions, manifest T-duality from world-sheet perspectives, and high energy scattering in AdS/CFT correspondence. Investigate applications of hyperbolic geometry in string theory, higher genus Gromov-Witten theory of quintic 3-folds, and generic properties of open string field theory solutions in level truncation. Learn about rolling near the tachyon vacuum, emergent geometries from string field theory including supergeometry and non-associative algebra, and nonperturbative definitions of closed string theory via open string field theory. Discover the underlying gauge theory of pure spinor superstrings, scattering amplitudes from intersection theory, and strings on celestial spheres. Study excited spin fields and twist fields as pointlike defects on worldsheets, string field theory and self-dual forms, and light-cone reduction of covariant string field theory. Explore the construction of new democratic theories, derivation of on-shell open string field amplitudes without Feynman rules, and closed string symmetries in open string field theory. Gain insights into finite size D-branes, heterotic string field theory with cyclic L-infinity structure, crossing symmetry in superstring theory, and gluing string amplitudes with coherent states.
