'''T. Thrivikraman (Thekkedath Thrivikraman)''' (born 6 May 1943, Died on 25 March 2024 ) was an Indian [[mathematician]] who has made important contributions to [[topology]], [[fuzzy mathematics]], [[history of mathematics]] and to several other areas of mathematics.<ref name=naos/> He actively promoted the culture of mathematical research in Kerala, himself guiding as many as 29 students in their doctoral research.<ref name=gen>{{cite web|title=Thekkedath Thrivikraman MathSciNet|url=https://www.genealogy.math.ndsu.nodak.edu/id.php?id=86761|website=Mathematics Genealogy Project|access-date=24 September 2016}}</ref> He was also actively involved in the activities of the science popularization movement known as [[Kerala Sasthra Sahithya Parishad]].<ref>{{cite web|last1=M C Nambudiripad|title=Namboothiris in the Mainstream of Science Popularisation|url=http://www.namboothiri.com/articles/science.htm|website=Namboothiri Websites Calicut|access-date=24 September 2016}}</ref>

==Early life and work on==
Thrivikraman was born in [[Arangottukara]], a small village in [[Thrissur district]] in [[Kerala State]]. After completing his Bachelor's studies in mathematics in Thrissur, he took his master's degree in mathematics from [[Kerala University]] in 1964. He started his mathematical career as a lecturer in mathematics in Mar Athanasius College, Kothamangalam, India, immediately after securing his master's degree. He availed leave from Mar Athanasius College and proceeded to [[Madurai Kamaraj University|Madurai University]] to pursue research in mathematics. Initially, he secured the [[Master of Philosophy]] degree in mathematics in 1969. He was awarded the [[Doctor of Philosophy]] degree in 1976 for his [[dissertation]] on "Studies in [[Compactification (mathematics)|Compactification]]s and other Extensions" written under the supervision of Prof. T. Soundararajan. In 1977 he moved over to the Department of Mathematics in [[Cochin University of Science and Technology]] where he held several positions until his retirement in
2003. After retirement from Cochin University of Science and Technology, he joined [[St. Joseph's College, Irinjalakuda]] to help develop a research centre in mathematics. Since 2009, he has been remaining active in mathematics by serving as a Visiting Professor in [[Kannur University]].

More than half of his doctoral students worked on various aspects of fuzzy mathematics. He helped push the boundaries of the theory to newer frontiers. Under his guidance and supervision, studies were conducted on various fuzzy mathematical structures like, fuzzy topology, fuzzy topological semigroups, fuzzy convexity, fuzzy inner-product spaces, fuzzy measures, fuzzy topological games, fuzzy commutative algebra, fuzzy matroids, etc.<ref name=gen/>

During the 79th Annual Conference of the [[Indian Mathematical Society]] held at [[Rajagiri School of Engineering & Technology]], [[Kochi]], during 28–31 December 2013, Thrivikraman, along with two other mathematicians from Kerala [[K. S. S. Nambooripad|Prof. K. S. S. Nambooripad]] and Prof. R. Sivaramakrishnan, were honoured in a special event called ''Guruvandanam'' for their lifetime contributions to mathematics.<ref>{{cite web|title=Guruvandanam|url=http://www.rajagiritech.ac.in/Home/Conf/Guru.asp|publisher=Organising Committee, 79th Annual Conference of IMS|access-date=25 September 2016}}</ref>

==Activities under the banner of Kerala Mathematical Association==
[[Kerala Mathematical Association]] is an organisation established in 1962 to serve the mathematical community comprising students, teachers and researchers inside Kerala and outside. Thrivikraman has been serving the Association as its Academic Secretary. In this capacity he has helped organize several national/international workshops and seminars in various colleges in different parts of Kerala.

==Science popularization efforts==
Thrivikraman is a life-member of Kerala Sasthra Sahithya Parishad. He organised a unit of the Parishad at Kothamangalam and also a Graama Saasthra Samithi there. He published many popular science articles in Malayalam dealing with mathematics in various journals. He contributed about 20 articles to the [[Malayalam]] [[encyclopaedia]] Viswa Vijnana Kosham published by National Book Stall, 8 articles to a Children's encyclopaedia published by STEPS. He authored two books on popular science and mathematics and also a book of poems.
