LU Decomposition (i). Prove that for n equal to 2 or 3 there is a non-singular square (n by n) matrix which has no LU decomposition with L unit lower triangular and U upper triangular. (In fact, this is true for any integer ≥ 2.) (ii). We will see that all non-singular square matrices do have an LUP decomposition (some time soon in class). Here P is a permutation matrix, also defined in Appendix D and used in Chapter 28....

a) Show that if A is a real, non-singular nxn matrix, then A.(A^T) is positive definite. b) Let H be a real, symmetric nxn matrix. Show that H is positive definite if and only if its eigenvalues are positive.

Let A be incidence matrix of graph G. prove if G has a cycle, then null space of transpose of A is not {0} (there exists non-trivial solution of (A^T)y=0)

Prove that if {xn} converges to x does not equal to 0 and xn is non-zero for all n, then there exists m > 0 so that |xn| ≥ m for all n.
