Hello, is there a mathematics course to be admitted to a master's degree in a research university after a bachelor's (short degree)?

Hi Karidja. This depends on the subjects/courses offered in the master's programme you are interested in at the research university. Nonetheless, do take note that, if you are required to do a Premaster's programme, which can be either for 6months or 1year before the start of your master's programme of your choice, the Premaster's programme will focus on Mathematics and English courses.
