Abstract
Abstract We study the question whether copies of $$S^{1}$$ S1 in $$\textrm{SU}(3)$$ SU(3) can be amalgamated in a compact group. This is the simplest instance of a fundamental open problem in the theory of compact groups raised by George Bergman in 1987. Considerable computational experiments suggest that the answer is positive in this case. We obtain a positive answer for a relaxed problem using theoretical considerations.
期刊介绍:
The Journal "Beiträge zur Algebra und Geometrie / Contributions to Algebra and Geometry" was founded in 1971 on the occasion of the 65th birthday of O.-H. Keller. It publishes research articles in the areas of algebra, geometry, algebraic geometry and related fields, preferably in English language.
The back issues of the journal are available at the European Digital Mathematics Library (EuDML) at:
