Zeros of Solutions of One of the Primary Equations of the First Order
摘要
Abstract
A central role in complex differential equations is given to the study of the number of zeros of analytic and meromorphic solitons. The situation is strikingly different for real ordinary differential equations. Until recently, the zeros of solutions of very few real ordinary resurrected equations (mostly of the second order) were considered. Particularly, the zeros of solutions of first-order equations were not considered at all. In this paper, we study the zeros for solutions of the following first-order basic equation
