An elementary proof of the Voros connection formula for WKB solutions to the Airy equation with a large parameter
arXiv:2205.02988
Abstract
The Voros connection formula for WKB solutions to the Airy equation with a large parameter is proved by using cubic equations. Some parts of the results are generalized to the Pearcey system, which is a two-variable version of the Airy equation, is given.
