Motzkin path on RNA abstract shapes
Sang Kwan Choi
We consider a certain abstract of RNA secondary structures, which is closely related to RNA shapes. The generating function counting the number of the abstract structures is obtain…
Interactions of Irregular Gaiotto States in Liouville Theory
Sang-Kwan Choi, Dimitri Polyakov, Cong Zhang
We compute the correlation functions of irregular Gaiotto states appearing in the colliding limit of the Liouville theory by using "regularizing" conformal transformations mapping…
RNA substructure as a random matrix ensemble
Sang Kwan Choi, Chaiho Rim, Hwajin Um
Combinatorial analysis of a certain abstract of RNA structures has been studied to investigate their statistics. Our approach regards the backbone of secondary structures as an alt…
Irregular conformal block, spectral curve and flow equations
Sang Kwan Choi, Chaiho Rim, Hong Zhang
Irregular conformal block is motivated by the Argyres-Douglas type of N=2 super conformal gauge theory. We investigate the classical/NS limit of the irregular conformal block using…
Virasoro irregular conformal block and beta deformed random matrix model
Sang Kwan Choi, Chaiho Rim, Hong Zhang
Virasoro irregular conformal block is presented as the expectation value of Jack-polynomials of the beta-deformed Penner-type matrix model and is compared with the inner product of…
Parametric dependence of irregular conformal block
Sang-Kwan Choi, Chaiho Rim
Irregular conformal block is an important tool to study a new type of conformal theories, which can be constructed as the colliding limit of the regular conformal block. The irregu…
