Gyula Pap

Gyula Pap (born 12 May 1954 in Debrecen, Hungary; died 4 October 2019) was a Hungarian mathematician and university professor at the Bolyai Institute of the University of Szeged. Pap was an expert in the field of probability theory.

Life Pap was born on 12 May 1954 in Debrecen. He attended the Mihály Fazekas High School and began studying mathematics at the University of Debrecen in 1972. He wrote his master's thesis in the field of stochastics under the supervision of Béla Gyires and graduated in 1977. In 1981, he began his doctoral studies at the Vilnius University in Lithuania under Vygantas I. Paulauskas, a leading expert in the field of stochastics in Banach spaces at the time. He received his PhD in 1985 with a dissertation titled Properties of Functions of the Distribution of the Norm of Stable Vectors in Banach Spaces.

At the University of Debrecen In 1986, Pap became an assistant professor at the University of Debrecen. In 1989, he was appointed associate professor, and after receiving his doctorate from the Hungarian Academy of Sciences, he was promoted to full professor in 1999.

From 1990 to 1991 and again from 2003 to 2009, he was head of the Department of Applied Mathematics and Probability Theory at the University of Debrecen. From 2003 to 2009, he was also Director of the Institute of Mathematics and Computer Science and, from 2004 to 2009, Vice Dean of the Faculty of Informatics.

At the Bolyai Institute of the University of Szeged In 2009, he moved to Szeged and served as head of the Department of Stochastics at the Bolyai Institute of the University of Szeged from 2009 to 2017.

He was also a member of the university choir and regularly played tennis in his free time.

Work Pap published works in many areas, including stochastics in Banach spaces and probability measures on Lie groups. From the 1990s onward, he primarily worked on statistical inference for stochastic processes, including time series, discrete and continuous branching processes, and stochastic differential equations.

He authored over 140 scientific papers and one monograph. He supervised 12 PhD students.
