DESCRIPTION:Speakers: YU NAKAYAMA (Yukawa Institute of Theoretical Physics
 )\n\nPlease be cautious of scams from individuals pretending to be travel 
 agency employees (e.g. Global Travel Team). They may try to steal your cre
 dit card number. No travel agency will contact you directly for this works
 hop. If a suspicious agency or person contacts you\, please confirm with u
 s. Please ignore any emails claiming to be related to this workshop unless
  they are sent from the domain yukawa.kyoto-u.ac.jp or by a member of the 
 Local Organizing Committee."\n \nOverview\nThe perturbative framework of 
 Quantum Field Theory and String Theory has been undeniably successful in d
 escribing fundamental interactions. However\, it is becoming increasingly 
 clear that a complete understanding of the physical universe—particularl
 y concerning Quantum Gravity and the vacuum structure of string theory—l
 ies beyond the reach of perturbative expansions. Asymptotic divergence in 
 perturbation theory is not merely a technical barrier but a signal of rich
 \, non-perturbative physics such as instantons and non-trivial saddle poin
 ts. To define the theory rigorously and uncover the fundamental degrees of
  freedom in gravity\, we must transcend the perturbative wall\; and develo
 p analytic tools capable of decoding the invisible sectors of the path int
 egral.\n \nThis workshop focuses on the powerful synergy between four int
 erconnected topics: Resurgence theory\, Matrix models\, String field theor
 y\, and Instantons. Recent developments have revealed that these areas are
  not isolated\; Resurgence provides the mathematical language to unify per
 turbative and non-perturbative sectors\, while Matrix models and String Fi
 eld Theory serve as ideal laboratories for testing these ideas in stringy 
 and holographic contexts. We will explore how D-instanton effects\, open-s
 tring tachyon condensation\, and the large-$N$ dynamics of matrices can be
  understood through a unified lens\, aiming to clarify the non-perturbativ
 e definition of superstring theory/M-theory. \n \nCoinciding with the th
 ree-month visit of Professor Xi Yin (Harvard University) to the YITP\, thi
 s one-week intensive workshop aims to bring together experts to tackle the
 se challenging problems. By combining the technical precision of formal th
 eory with the intuitive leaps required for breakthroughs\, we hope to gene
 rate what we playfully call Really Marvelous Sparkling Ideas\; (RMSI). The
  goal is not only to share recent progress but to foster deep discussions 
 that spark a new understanding of the non-perturbative landscape of high-e
 nergy physics.\n\nSpeakers\n \nAmr Ahmadain\nNathan Berkovits (TBC)\nMinj
