International Workshop on Operator Theory and its Applications (IWOTA) was started in 1981 to bring together mathematicians and engineers working in operator theoretic side of functional analysis and its applications to related fields. These include: * Differential equations and Integral equations * Complex analysis and Harmonic analysis * Linear system and Control theory * Mathematical physics * Signal processing * Numerical analysis The other major branch of operator theory, Operator algebras (C* and von Neumann Algebras), is not heavily represented at IWOTA and has its own conferences.
