A GREETING TO PROFESSOR IVAN K U ~ E R ON THE OCCASION OF HIS 60th BIRTHDAY

It is with great pleasure that we wish Ivan Ku/~6er, Professor of Physics at the University of Ljubljana, birthday greetings. This versatile man has worked with many scientists and mathematicians the world over and all have benefited

from his insight into physical problems, He has particularly assisted young scientists in their careers by stimulating independent enquiry but nevertheless always being ready with a helping hand when needed. We all wish him many more years of active scientific work (and mountaineering).
