Dear Colleague,

we would like to invite you to take part in the Fourth Najman Conference on Spectral Problems for Operators and Matrices, to be held from September 20-25, 2015 in Opatija, Croatia.

The purpose of this conference is to commemorate the scientific contribution of Branko Najman by bringing together scientists working in areas of mathematics related to his work, with an emphasis on the following fields of research:

  • General operators and spectral theory, structured operators and matrices
  • Indefinite inner product spaces
  • ODEs and Sturm-Liouville theory
  • Elliptic PDEs including Schrödinger operators
  • Evolution equations, semigroups, control theory
  • Matrix analysis
  • Numerical methods related to any of the above.

The conference will feature plenary lectures by distinguished speakers, contributed talks, and a poster session. The invited plenary lectures will be presented by

  • Wolfgang Arendt
  • Albrecht Böttcher
  • Zlatko Drmač
