Budi Surodjo



Dr. Budi Surodjo, MSi. is an Associate Professor in the Mathematics Department, Faculty of Mathematics and Natural Science, Universitas Gadjah Mada, Yogyakarta Indonesia. He has been joined the Department since 1991 until today. His expertise is in the field of algebra, particularly fuzzy logic, semigroup theory and generalized power series modules. His undergraduate and Doctor degrees were received from Universitas Gadjah Mada Yogyakarta Indonesia in 1990 and 2006, respectively. He got his master degree from Institut Teknologi Bandung in 1995. 


Research interests

Current research interests include generalized power series modules, monoid with indexed matrices, generalized basis, and the topological structure of generalized power series rings. Present focus is on injectivity  of topological module and generalized power series of max plus algebra and their applications.
