isomorphism

Last edited: August 8, 2025

An isomorphism is an invertable Linear Map. Two vector spaces are called isomorphic if there is an isomorphism from one to another.

“A linear map that maintain the correct structure of the structure.”

This makes the vector spaces that are isomorphic “equivalent”, because the isomorphism is the equivalence relationship. Of course, they are still not equal.

Generally, isomorphisms can only be built between vector spaces over the same field.

additional information

matrices

We know we can represent Linear Maps as matricies.

So, given some \(A\), we have an inverse \(A^{-1}\).

If a student has ability \(a\), and a probably is \(d\) difficulty, the probability of a student getting something right:

\begin{equation} \sigma (a-d) \end{equation}

this doesn’t consider SLIPPING at all.
