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. The journal is organised in six sections, published in the form of topical collections: Higher Dimensional Geometric Function Theory and Hypercomplex Analysis Infinite-dimensional Analysis and Non-commutative Theory Linear Operators and Linear Systems Operator Theory and Harmonic Analysis Reproducing Kernel Spaces and Applications Spectral Theory and Operators in Mathematical Physics.
