The discussion focuses on solving the matrix equation C^TA - XB = B^{-1} - X for X. The user successfully rearranged the equation to isolate X, resulting in X = (C^TA - B^{-1})(B-I)^{-1}, contingent on the invertibility of B-I. Participants confirm the user's solution is correct under the given assumption. The user expresses a desire for similar examples online but notes difficulty finding them. This highlights a potential gap in available resources for such matrix equation problems.

I have to express $X$ in given matrix equation:

$$C^TA-XB=B^{-1}-X$$

I have done this,and i don't know if i have done it good:
$$C^TA-B^{-1}=XB-X$$
$$C^TA-B^{-1}=X(B-I)$$

$$(C^TA-B^{-1})(B-I)^{-1}=X$$

Thank you for the help and answers!

Yes, that is correct (assuming, as you have to, that $B-I$ is invertible).

Thank you! I really hope it is correct! ;)

I haven't noticed similar examples on the internet,do you maybe know where i could find them?

I am studying the mathematical formalism behind non-commutative geometry approach to quantum gravity. I was reading about Hopf algebras and their Drinfeld twist with a specific example of the Moyal-Weyl twist defined as F=exp(-iλ/2θ^(μν)∂_μ⊗∂_ν) where λ is a constant parametar and θ antisymmetric constant tensor. {∂_μ} is the basis of the tangent vector space over the underlying spacetime Now, from my understanding the enveloping algebra which appears in the definition of the Hopf algebra...
