Control theory
The matrix exponential and linear differential equations, convergent and power-bounded matrices, the Sylvester and Lyapunov equations, the spectral radius, and Krylov subspaces.
It aims at 10.9 Functions of Matrices, the Exponential and Linear Differential Equations, 10.10 Convergent and Power-Bounded Matrices, 12.10 The Sylvester Equation, 16.4 The Spectral Radius, 24.6 Krylov Subspaces.
99 sections to read, of 236. That is everything the proofs of those sections rest on, and nothing else.
135 if you also work the exercises, since a written solution is the proof of its exercise: 36 more sections.
What to read
In reading order. Bold marks a section the path is aimed at; + marks one that only the exercises need. The note beside a section says when the whole path hangs on a single proof citing it.

What you can skip
137 of the book's 236 sections are not on this path, and skipping them costs you no proof you need.
Not needed at all: Tensors and Exterior Algebra, Matrix Inequalities, Affine and Projective Geometry, Algebras and Representations.
Cited in passing by sections on the path — in a statement, a remark or an example, never in a proof — so they are context and not prerequisites: 11.10 Orthogonal Polynomials, 13.12 Projections Revisited, 20.4 The Bauer–Fike Theorem, 24.1 Floating Point and Backward Error.
Computed from the book's proofs when the book was built, and checked: every result a proof on this path uses is proved by another section on this path. The other paths are listed on the reading paths page.
