Notes on phase structure and non-vanishing functions of one-unitary matrix model
Hiroshi Itoyama, Reiji Yoshioka
Unitary matrix models, among other things, play an important role in representing the irregular conformal block and hence LEEA of some asymptotically free susy gauge theories. Here…

Fermionic modes of D-instanton wormholes from broken local supersymmetry
H. Itoyama, Hikaru Kawai, Shoichi Kawamoto
In low-energy supergravity treatment of type IIB superstring on general D-instanton wormhole profiles in the bulk, we obtain non-vanishing scalar two-point functions in addition to…

Phases and triple(multiple) point: critical phenomena around the AD singularity
Hiroshi Itoyama, Reiji Yoshioka
Continuing with our previous series of work, we present a case study of the critical phenomena around Argyres-Douglas singularity of susy made at $(A_1, A_{4k-1} ), k…
