PROF. MARIEN ABREU FROM DEGLI STUDI DELLA BASILICATA UNIVERSITY ITALY GAVE A SEMINAR AT CTS FMIPA ITB
BANDUNG, fmipa.itb.ac.id, -Combinatorics Today Series (CTS) is a regular international seminar activity held by the Combinatorial Mathematics Research Group, Faculty of Mathematics and Natural Sciences (FMIPA), Institut Teknologi Bandung (ITB), in collaboration with Pusat Kolaborasi Riset Teori Graf dan Kombinatorika Indonesia (Center for Indonesian Graph Theory and Combinatorics Research Collaboration). This is the 3rd year that this international seminar series has been running. Throughout 2023, this online activity will provide 11 editions. This activity is carried out to improve the reputation of this research group in the development of graph theory science on the world stage. Therefore, Prof. Edy Tri Baskoro as Chair of the committee for this activity presented a number of well-known speakers from various parts of the world. This seminar aims to increase knowledge of the development of various topics in the field of graph theory which could be an initiation effort to collaborate together in the future. On Friday, July 7, 2023, for this 5th CTS activity, a lecturer and researcher from the European continent was invited. This activity was held in a hybrid manner, where participants could attend offline in the study hall room of the CAS building and via zoom.
Prof. Marien Abreu is a researcher in the field of combinatorics from degli Studi della Basilicata University, Italy. She has been a researcher since 2010-2021 at degli Studi della Basilicata University, adjunct professor at the Taranto Campus in 2009-210, and is a teaching assistant at the Department of Mathematics Science, Florida Atlantic University, USA. Apart from that, during her career as a researcher, she has had around 41 articles in reputable journals. The title of the presentation was “Extending perfect matchings to Hamiltonian cycles”. The presentation started with a brief explanation about her home campus, an introduction containing definitions and examples of graphs that will be used in research on this topic, to several results that have been produced. A graph is said to have perfect matching, then each perfect matching can be expanded into a Hamiltonian cycle called Perfect-Matching-Hamiltonian (abbreviated as PMH). Graphs with these properties have been studied since the 1970s by Las Vergnas and Haggkvist, where they called them Hamiltonians. At the end of her presentation, Mauren provided a multitude of interesting open problems to study in this field.
This webinar was attended by around 40 online participants consisting of lecturers, researchers, and undergraduate and graduate students from various countries such as Indonesia, Australia, Thailand, China, and several other countries.
