报告题目:­­­ Homotopy Operator and Applications

地 点: 数学系会议室(格物楼503

报告摘要:In recent years, much progress has been made in the study of differential forms and the related operators, such as the homotopy operator, Green’s operator and potential operator. Among these operators, the homotopy operator is a critical one. It is well known that any differential form u can be decomposed as u = d(Tu) + T(du), where d is the differential operator and T is the homotopy operator. Therefore, the homotopy operator provides an effective tool to study various properties of different forms and the related operators. As extensions of functions, differential forms have become invaluable tools for many fields of sciences and engineering, including theoretical physics, general relativity, potential theory and electromagnetism. They can be used to describe various systems of PDEs and to express different geometrical structures on manifolds. The purpose of this talk is to present an up-to-date account of the recent advances made in the study of the homotopy operator and its compositions applied to differential forms.
