Introduction to Tensor Calculus - arXivorg
Rank-2 tensors may be called dyads although this in common use may be restricted to the outer product of two vectors and hence is a special case of rank-2 tensors assuming it meets the requirements of a tensor and hence transforms as a tensor Like rank-2 tensors rank-3 tensors may be called triads

If rank(A)< m then thesystem would have a free variable meaning that if there is a solution then there arein nitely many solutions 4 If the system has in nitely many solutions then rank(A)< m because a system within nitely many solutions must have a free variable
1803 LA2: Matrix multiplication rank solving linear systems
Rankof A= the number of independent columns of Athe number of independent rows of A The process of row reduction provides the algebra the mechanical stepsthat make it obvious that the matrix in example 5 has rank 2! The steps ofrow reduction don't change the rank because they don't change the numberof independent rows!

rank(AB) ? min rank(A)rank(B) Proof: Since (AB)x = A(Bx) for any column vector x of an appropriate dimension we have LAB = LA LB Therefore this theorem is a corollary of the theorem from the previous slide Theorem 2 Let A ? Mmn(F) Then for any invertible matrices B ? Mnn(F) and C ? Mmm(F) rank(A) = rank(AB) = rank(CA) = rank(CAB)

Is tensor rank invariant?
- The tensor rank has the property of being invariant from this fact. Moreover, from Proposition 3.1 we know that tensor rank is preserved when a tensor space is included in a larger tensor space. Similar assertions are true for the multilinear rank (cf. (2.19)).
What is the value of a if rank(a 1) = 1?
- If rank(A 1)=0, then A= 00 00 Using matrix operations,Amust then be equivalent to one of the forms (depending on rank(A 2)) 00 00 00 00 10 00 00 01 , D 0,1, and2, respectively (after reordering the slabs). If rank(A 1) = 1, then we may assume that A= 10 00 ab cd 10 00 10 00 00 1
What is the rank of a matrix?
- Let’s introduce a new term the rank of a matrix. Rank of A = the number of independent columns of A. Example 6: Find the row echelon form of 2 4 1 3 4 12 3 9 3 5: But what do you notice about the rows of this matrix? We made this matrix by making the columns dependent.
