15) 2. if p > n we have D=0 Proof. It follows directly from Laplace’s theorem. 16. 16). 17. 16). 17) in n unknowns x1 , x2 , . . , xn ∈ R and m × n coefficients aij ∈ R. An n-tuple x1∗ , x2∗ , . . 17) if, upon substituting xi∗ instead of xi (i = 1, . . 17), equalities are obtained. 17) may have • a unique solution; • infinitely many solutions; • no solutions (to be inconsistent). 9. 17) if their sets of solutions coincide or they do not exist simultaneously. It is easy to see that the following elementary operations transform the given system of linear equations to an equivalent one: • interchanging equations in the system; • multiplying an equation in the given system by a nonzero constant; • adding one equation, multiplied by a number, to another.

P) are called the leading principal minors. 8. 15. 1. (Laplace’s theorem) Let A be an arbitrary n × n matrix and let any p rows (or columns) of A be chosen. 13) n! distinct sets of column indices p! (n − p)! 14) where 1 ≤ i1 < i2 < · · · < ip ≤ n Proof. 10). 2. (Binet–Cauchy formula) Two matrices A ∈ Rp×n and B ∈ Rn×p are given, that is, ⎡ a11 a12 ⎢ a21 a22 A=⎢ ⎣ · · ap1 ap2 ⎤ · a1n · a2n ⎥ ⎥, · · ⎦ · apn ⎡ b11 b12 ⎢ b21 b22 B=⎢ ⎣ · · bn1 bn2 ⎤ · b1p · b2p ⎥ ⎥ · · ⎦ · bnp Determinants 15 Multiplying the rows of A by the columns of B let us construct p 2 numbers n cij = aik bkj (i, j = 1, .

The second formula, when det D = 0, may be proven by the analogous way taking into account the decomposition Matrices and matrix operations A C B I = D O BD −1 I A − BD −1 C O O D I D −1 C For proofs of formulas three and four see Gantmacher (1990). 2. (on the inversion of a block-matrix) If S := S11 S12 , S21 S22 S11 ∈ Rl×l , S22 ∈ Rk×k then A B C D −1 S21 A = S11 − S12 S22 S −1 := −1 ∈ Rl×l −1 ∈ Rk×k −1 B = −S11 S12 D −1 S21 A C = −S22 −1 S12 D = S22 − S21 S11 provided by the condition that all inverse matrices exist.
