Fyrirlesari: Ragnar Sigurðsson (Háskóla Íslands)
Stað- og tímasetning: 4. apríl kl. 11:40 í Oddi O-106.
Titill: The work of Sigurður Helgason on the Radon transformation.
Ágrip: The Radon transformation is the main mathematical tool behind medical morphology. Sigurður Helgason made a major contribution to the theory of the Radon transform which had great impact on both theoretical aspects and applications. In the lecture I will discuss the Radon transformation and try my best to explain the applications. If I have time, then I will talk about Helgason’s supporting theorem and my generalization of it using techniques from complex analysis and pluripotential theory.
