# The non-Abelian T-dual of Klebanov-Witten Background and its Penrose Limits

## TL;DR

This paper explores non-Abelian T-duals of the Klebanov-Witten background, analyzes their Penrose limits, and investigates string quantization on resulting pp-wave backgrounds to understand potential dual field theories.

## Contribution

It provides a detailed study of non-Abelian T-duals of Klebanov-Witten backgrounds and their Penrose limits, including string quantization and dual field theory implications.

## Key findings

- Existence of pp-wave solutions near null geodesics
- Quantization of strings on these backgrounds
- Insights into dual field theories

## Abstract

In this paper we consider both Abelian as well as non-Abelian T-duals of the Klebanov-Witten background and inspect their various Penrose limits. We show that these backgrounds admit pp-wave solutions in the neighbourhood of appropriate null geodesics. We study the quantization of closed string propagating on some of the resulting pp-wave backgrounds and comment on the probable field theory duals.
