ICPTSOHC 2020 : International Conference on Perturbation Theory, Second-Order and Higher Corrections is the premier interdisciplinary platform for the presentation of new advances and research results in the fields of Perturbation Theory, Second-Order and Higher Corrections. The conference will bring together leading academic scientists, researchers and scholars in the domain of interest from around the world. Topics of interest for submission include, but are not limited to:
-
