Håkan Hedenmalm (born August 25, 1961 in Karlstad) is a Swedish mathematician. Career Hedenmalm has mainly contributed to the development of the theory of Bergman spaces and the associated reproducing kernels in one complex variable. In 1996 he became a professor at Lund University and in 1997 he was elected to KFS, the Royal Physiographic Society in Lund. Later, in 2018, he was elected to DKNVS, the Royal Norwegian Society of Sciences and Letters in Trondheim. Hedenmalm has collaborated with a number of other mathematicians, in particular with Alexander Borichev, Serguei Shimorin and Nikolai Makarov. Since 2002 he is professor at the Royal Institute of Technology (KTH) in Stockholm. He has had a number of PhD students. One of them is Ali Abkar. Distinctions He received the Wallenberg Prize in 1992, and in 1996 he was invited speaker at 2ECM (second European Congress of Mathematicians) in Budapest. In 2000 he received the Göran Gustafsson Prize (KVA). In 2015, he received the Eva and Lars Gårding Prize from KFS, the Royal Physiographic Society in Lund.
