 Tatsuki Kuwagaki 
 from Kavli IPMU will be presenting a lecture 
 titled "Sheaf quantization from spectral 
 network." \n
 \n
 A sheaf quantization is a sheaf 
 associated to a Lagrangian brane. This sheaf 
 conjecturally has information as much as Floer 
 theory of the Lagrangian. On the other hand, 
 exact WKB analysis is an analysis of differential 
 equations containing the Planck constant 
 hbar. In this talk, I will explain how 
 to construct a sheaf quantization over the Novikov 
 ring of the spectral curve of an hbar-differential 
 equation, by using the ideas of exact 
 WKB analysis and spectral network. In the 
 construction, one can see how (conjecturally) 
 the convergence in WKB analysis are related 
 to the convergence of Fukaya category. In degree 
 2, the sheaf quantization associates a 
 cluster coordinate which is the same as Fock-Goncharov 
 coordinate. I will also mention about 
 some relationships to Riemann-Hilbert correspondence 
 of D'Agnolo-Kashiwara and Kontsevich-Soibelman.\n\n
