Pei Yuan Wu achieved significant, deep results in a wide range of
operator theory, including dilation theory of contractions, sums and
products of operators, and numerical ranges of operators and matrices.
He contributed twelve definitive research papers to the
Acta Scientiarum Mathematicarum,
ten of them strongly connected with the Sz.-Nagy--Foias theory of Hilbert space contractions,
enriching it with beautiful, fundamental results.
The Medal was presented to Pei Yuan Wu
at 15:00, May 12, 2016
in the Bolyai Institute.
On this occasion he delivered a lecture
``$S_n$-matrices: numerical range, dilation and compression".
