It is possible for multiple PhD students to obtain their PhD degrees based on a single publication, but it depends on various factors such as the specific regulations and policies of the university or academic institution where they are enrolled.

In some cases, collaborative research work conducted by multiple PhD students may lead to a joint publication. This can occur when the research is interdisciplinary or when multiple students have contributed significantly to the project. In such cases, universities may have provisions that allow multiple PhD students to include the joint publication as part of their doctoral theses.

However, it’s important to note that the requirements for obtaining a PhD degree typically go beyond publishing papers. A PhD program generally involves a comprehensive examination, coursework, and a thesis or dissertation that demonstrates the student’s original research contribution and ability to critically analyze and synthesize knowledge in their field. The specific requirements and expectations vary across institutions and disciplines.

Ultimately, the possibility of multiple PhD students obtaining their degrees based on a single publication depends on the policies and guidelines set by the academic institution and the approval of the respective faculty or committee overseeing the PhD program. It is advisable to consult with the relevant faculty or administrative staff at the specific institution to understand their policies and guidelines regarding this matter.
