PUBLICATIONS:

• He has written over 100 papers published in Romania and abroad dealing especially with functional analysis and published 15 books. The main books are the following:

• Ordered vector spaces and linear operators (Abacus Press, Kent, England 1976),

• Topological vector spaces (Noordhoff, The Netherlands 1977),

• Applications of the theory of distributions (with G.Marinescu) (John Wiley, London, New York 1973),
