A note on Zamolodchikov's recursion relation for the torus conformal block and its light limit

Armen Poghosyan, Hasmik Poghosyan

In this paper, we review the Zamolodchikov-like recursion relations for torus one-point conformal blocks in both Liouville and Toda theories. Starting from these relations, w…

The Light One-Point Torus Conformal Block

Armen Poghosyan, Hasmik Poghosyan

We study the light asymptotic limit of the one-point torus conformal block in Toda field theory. Through the AGT correspondence, this problem can be translated into the c…

On 5-point conformal block with level 2 degenerate field insertion and its AGT dual

Hasmik Poghosyan, Rubik Poghossian

In this paper, we develop and explore recursive methods to investigate the 2d CFT 5-point conformal block with a level 2 degenerate insertion, as well as its AGT dual, by solving t…

Resumming Post-Minkowskian and Post-Newtonian gravitational waveform expansions

Andrea Cipriani, Giorgio Di Russo, Francesco Fucito +3

We derive formulae that resum, at a given order in the soft limit, the infinite series of Post-Minkowskian (small gravitational coupling) or Post-Newtonian (small velocities) corre…

A note on rank 5/2 Liouville irregular block, Painlevé 1 and the Argyres-Douglas theory

Hasmik Poghosyan, Rubik Poghossian

We study 4d type Argyres-Douglas theory in -background by constructing Liouville irregular state of rank 5/2. The results are compared with generalized Holomorphic…

Exact expressions for the 5-Point Liouville conformal block with a level-two degenerate field insertion

Hasmik Poghosyan, Rubik Poghossian

In this paper we investigate 5-point Liouville conformal block with a level 2 degenerate field insertion. Our main tool is the BPZ differential equation, which, upon placing three…
