Module fixed_point 

Fixed-Point Detection and Stability Analysis

Linearize the RG flow around fixed points. Eigenvalues of the linearized flow determine relevant vs irrelevant directions.

Structs

FixedPoint

A fixed point of the RG flow.

Enums

DirectionClass

Classification of RG flow directions.

Functions

analyze_stability

Analyze stability around a known fixed point. Computes eigenvalues and classifies directions.

find_fixed_point

Find a fixed point by iterating the flow equation. Returns None if the iteration doesn’t converge.

is_near_fixed_point

Test if a given parameter vector is near a fixed point.
