Title: Form of solutions to quadratic trinomial partial differential equations with two complex variables Authors: Jin Tu (Jiangxi Normal Univ., Nanchang Jiangxi, China) Huizhen Wei (Jiangxi Normal Univ., Nanchang Jiangxi, China) Abstract: This article describes the from of entire solutions to quadratic trinomial partial differential equations (PDEs). By applying the Nevanlinna theory and the characteristic equation of PDEs, we extend some of the results obtained in [24]. Also we provide examples that illustrate our results.
