    The Maximum Rank of a Matrix B Given AB=0 and A is a Full Rank Matrix

    Sorry about that. I mean a a 2 x 7 matrix. That way the numbers would change a bit. So, in this case(Your new example), the Rank(A) = 3, Rank(B) = unknown and the Rank(AB) = 0. Which is exactly the same as the previous example. I appreciate your help but I think that I am going to read...

    The Maximum Rank of a Matrix B Given AB=0 and A is a Full Rank Matrix

    So, if Matrix A were instead a 8 x 3 matrix, then B would have a rank of five? What I am seeing is that it is the subtraction of columns from rows in order to find the rank of B that maps A to 0?

    The Maximum Rank of a Matrix B Given AB=0 and A is a Full Rank Matrix

    Homework Statement Suppose that AB = 0, where A is a 3 x 7 full rank matrix and B is 7 x 53. What is the highest possible rank of matrix B. Homework EquationsThe Attempt at a Solution Since each column of B is in the null space of A, the rank of B is at most 4. I don't understand why it is...

    Is There a Chat Room for Physics and Math Enthusiasts?

    Howdy all, I found this forum and thought I'd give it a spin. I love physics and mathematics but I am a bit rusty. Just looking to pick up some cool skills and solve some neat problems.
