    Matrix of. Linear operator question

    I am trying to figure out what the matrix of this linear operator would be: T:M →AMB where A, M, B are all 2X2 matrices with respect to the standard bases of a 2x2 matrix viz. e11, e12 e21 and e22. Any ideas? Il know it should be 2X8 matrix. I am trying to teach myself Abstract algebra using...

    Prime Divisibility Property: Proving p^2 divides a^p - b^p for Integers a and b

    This is a weird coincidence since i was trying to solve a similar problem which is: Prove that if a ^ p + b ^p = 0 (mod p) then a ^ p + b ^p = 0 (mod p ^ 2) The logic is exactly similar i guess except that p as to be odd & greater than 2. Can somebody please look into & give me clues to...

    Proving the Chinese Remainder Theorem for Reduced Residues Modulo mn

    I am teaching myself number theory using George Andrews book. i am stuck in the following problem: To prove that as x cycles thru' the reduced residue set modulo m & y cycles thru' reduced residue set modulo n, nx + my cycles thru' reduced residue set modulo mn. I am able to prove that...
