ICTP Prize Winner 1992

The ICTP Prize in honour of V.F. Weisskopf (USA) in the field of High Energy Physics was awarded to Elcio Abdalla, Universidade de São Paulo, Brazil, in recognition of his contributions in the field of high energy physics. He proved that the CPn model has a quantum anomaly and showed its cancellation in supersymmetric case. He has also constructed the supersymmetric extension of the Wess-Zumino term. More recently he dealt with correlation function in non critical superstrings, computing the correlators in super Liouville theory. The general problem of two dimensional gravity has also been treated. He has written a book on two dimensional quantum field theory which was intended to emphasize the relations of this field with more realistic models, as well as to explicit the difficulties in this area, specially concerning non perturbative aspects.
