SUMMARY
The defect of a linear transformation refers to a defective matrix that lacks a complete basis of eigenvectors. Specifically, the defect is defined as the codimension of the transformation's range. In finite-dimensional spaces, the rank theorem establishes that the defect is equivalent to the nullity of the operator, which is the dimension of its kernel. Understanding these concepts is essential for analyzing the properties of linear transformations in linear algebra.
