# Bohuslav Balcar (1943-2017)

With deep sorrow we inform that Dr. Bohuslav Balcar passed away on Friday, February 17th, 2017.

Bohuslav Balcar was born in 1943. In 1965 he finished his studies at the Charles University in Prague under the supervision of P. Vopěnka. Although he obtained a degree in numerical mathematics, his main interests were mathematical logic, automata theory, and set theory. He was one of the original members of the Prague set theory seminar founded by P. Vopěnka in 1962. Between 1965 and 1975 he was a member of several departments at the Faculty of Mathematics and Physics of the Charles University, and in 1975 he started working at ČKD Semiconductors. While employed at the `factory’ as he liked to call the company, he was awarded the Candidate of Sciences (PhD) degree for his work on the theory of semisets, participated in a section of the `national fundamental research plan’ directed by Z. Frolík, and published his most important results. Together with P. Simon he lead the Seminar on Reckoning at Charles University, participated and later organized the Winter Schools in Abstract Analysis and Prague Topological Symposia. In 1989 he was awarded the Doctor of Science degree and started working in the Institute of Mathematics of the Czech Academy of Sciences. Since 1992 he was a member of the the Institute for Advanced Studies, joint research institute of the Charles University and the Czech Academy of Sciences.

Bohuslav Balcar’s mathematical interests included set theory, Boolean algebras, topological dynamics, and logic foundations. He officially supervised five graduate students, and many more had earned their degree under or benefited from his unofficial supervision. His influence shaped several generations of Czech set theoreticians.

Bohuslav Balcar was a kind, inspirational, and unresentful man. He will be greatly missed.

# Matti Rubin (1946-2017)

We are sorry to inform you that our colleague Matti Rubin from Ben-Gurion University of the Negev, Israel died on 6th of February, 2017.

**adieu Mati, by Robert Bonnet**

Dear Friends,I have lost my best friend Mati, who was one of the deepest mathematicians that I knew. These news have saddened all mathematicians, and in particular his friends.

Mati Rubin was born in September 1946, he studied in Ben Gurion University and University of Colorado with Don Monk, and he obtained his PhD under the supervision of Saharon Shelah.

He was a fantastic and deep mathematician, explaining all ideas, results and proofs in details to all colleagues interested.

He published fifty papers in different subjects, some of them in collaboration, with 26 co-authors, including Saharon Shelah and J. Don Monk.

His domains of research cover Mathematical logic, Set theory, Ordered algebraic structures, General topology and Group theory and generalizations. He was a specialist in Set theory, Boolean algebras and Reconstruction results from their automorphism groups. Some of his work is left unfinished.

With all my best wishes, Robert
