 \nTitle: Emergence of Classical and Quantum Spacetimes in IKKT Matrix Mode
 ls\n\nAbstract:\nThe Ishibashi-Kawai-Kitazawa-Tsuchiya (IKKT) matrix model
  is a promising nonperturbative formulation of type IIB superstring theory
 \, in which spacetime is expected to emerge dynamically from the distribut
 ion of matrix eigenvalues\, which are interpreted as the positions of D-in
 stantons. Understanding how these matrix degrees of freedom organize into 
 different spacetime structures is one of the central questions in the mode
 l. \nIn this talk\, I will present a series of recent works that address 
 this question from several complementary perspectives. I will first discus
 s the supersymmetric mass-deformed (polarized) IKKT model with Monte-Carlo
  numerical method\, which reveal the interplay among fuzzy-sphere\, IKKT\,
  and commuting-matrix saddle configurations and their implications for eme
 rgent spacetime. \nI will then show how the Wilson loop in two-dimensiona
 l bosonic IKKT (Hoppe) matrix model reproduces continuum Yang-Mills theory
  through large-N reduction. Finally\, we move on to the higher-dimensional
  bosonic IKKT model\, where recent progress sheds new light on the nonpert
 urbative dynamics of D-instantons and the microscopic structure of quantum
  spacetime.\nTogether\, these studies illustrate how the dynamics of matri
 x eigenvalues provides a unified framework for understanding the emergence
  of both classical and quantum spacetime in IKKT matrix models.\n\nhttps:/
