Complex Analysis and Operator Theory (CAOT) is devoted to the publication of current research developments in the closely related fields of complex analysis and operator theory as well as in applications to system theory, harmonic analysis, probability, statistics, learning theory, mathematical physics and other related fields. Articles using the theory of reproducing kernel spaces are in particular welcomed.

CAOT is organised in the following six sections, which are published in the form of “topical collections”:

  • Harmonic Analysis and Operator Theory 
  • Higher Dimensional Geometric Function Theory and Hypercomplex Analysis
  •  Infinite-dimensional Analysis and Non-commutative Theory
  • Linear Operators and Linear Systems
  • Reproducing Kernel Spaces and Applications
  • Spectral Theory and Operators in Mathematical Physics

Accepted papers will be published in the most appropriate section.
