Let A,B be complex n,n complex matrices such that AB-BA and A commute. We show that, if n=2 then A,B are simultaneously triangularizable and if n>=3 then there exists such a couple A,B such that the pair (A,B) has not property L of Motzkin-Taussky and such that B and C...
If {eq}A=\{1,2,3\} {/eq} and {eq}B=\{a, b, c, d\} {/eq}, what is {eq}|P(A \times B)| {/eq}? Power Sets: Given a set {eq}S {/eq}, the power set {eq}P(A) {/eq} is defined to be the set of all subsets of the original set {eq}A {/eq}. In set-...
An easy exclusion criterion is a matrix that is not nxn. Only a square matrices are invertible (have an inverse). For the matrix to be invertible, the vectors (as columns) must be linearly independent. In other words, you have to check that for an nxn ma

Risk management plays a critical role in reducing the impact of disasters. Among its many benefits are to identify and evaluate the potential effects of disasters, to establish early warning systems, and to put in place potential response mechanisms, such as financing arrangements, prior to their ...
If both, a and b, has been allocated as type "Sigma_Type_A", the program runs fine invaribaly of the size of the relevant arrays. Moreover, threaded or unthreaded the pogram always runs when the involved arrays are small. However, when arrays occupy up to 200GB of RAM and ...
