On the Complexification of Linear Operators and its Applications
Wednesday 11th November 2025 at 14:15
Abstract. The aim of this talk is to demonstrate how the complexification procedure can be used to derive important properties of operators acting on a real Hilbert space from their counterparts in the complex setting. In particular, we will outline how the spectral representation theorem for real Hilbert spaces can be derived from its complex version. Although this result is often regarded as part of mathematical folklore, it nonetheless requires some explanation.
At the department meeting room (2nd floor Z205), Žižkova 17.
