Maka Tetradze, PhD Candidate at Chikobava Institute of Linguistics and visiting researcher at Malmö University, and Prof. Karina Vamling (Malmö University) have visited archives in Oslo, an active center for research on the languages of the Caucasus in the mid 1920s up to the beginning of the 1980s. For several decades the Institute for Comparative Research in Human Culture in Oslo hosted a programme on Caucasology. The most prominent researchers were prof. Hans Vogt (1903-1986), Alf Sommerfelt (1892-1965) and later Fridrik Thordarson (1928-2005), who were also working at Oslo University. Prof. Hans Vogt is most known as the author of “Dictionnaire de la langue oubykh” (1963) and “Grammaire de la langue géorgienne” (1971), whereas Prof. Alf Sommerfelt focused on North-East Caucasian Languages and Fridrik Thordarson devoted most of his research to Ossetic.
