Prerequisite chain

Prerequisites for Spectral Theory of Operators

Topics you need before working through Spectral Theory of Operators. Direct prerequisites are listed first; transitive prerequisites (the chain reachable through them) follow.

Direct prerequisites (3)

Eigenvalues and Eigenvectorslayer 0A, tier 1
Complex Numbers for Fourierlayer 0A, tier 2
Functional Analysis Corelayer 0B, tier 2

Reachable through the chain (14)

These topics are not directly cited as prerequisites but are reached transitively by following the chain upward. Working through the direct prerequisites pulls these in.
