Determinants between two similar matrices

Click For Summary
Two 4×4 matrices A and B with identical rows do not necessarily have equal determinants, as the determinants depend on all elements of the matrices. The presence of identical rows in one matrix does not imply that the determinants of both matrices are related, especially if the other rows differ. Row operations can be performed to manipulate the matrices, potentially leading to equal determinants under certain conditions. The discussion highlights the importance of understanding how determinants are calculated and the role of all matrix elements. Ultimately, the relationship between the determinants of two matrices with identical rows is not straightforward.

Lets suppose a 4×4 matrix A has two identical rows with some other 4×4 matrix B. Does that imply there determinant is equal? Or does it really say nothing about how the determinants of the two matrices are related.

As long as the other rows may be different, the determinants may be different.
 
Why should two identical rows imply equality of determinants? The value of the determinant involves ALL of the elements of a matrix.
 
I mistakingly asked this question prematurely--not releasing that I could of easily performed row operations to enable the determinants of the two matrices to be the same.
 
So would you mind now telling us what the question really is?
 

Thread 'Confusion about the Moyal-Weyl twist'

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...
