mathematics - advanced determinant calculus

... Vandermonde determinant is that there are so many (to be precise: n)variables at our disposal. On the contrary, the determinant in (2.19) has exactly one (!) variable.’ ADVANCED DETERMINANT CALCULUS ... c[3], -1 0 c[1] + 2 c[3], -5 c[1] + c[3], c[1]} In[7]:= V[8] Out[7]= {0, c[1], 6 c[1], c[3], -2 5 c[1] + 3 c[3], c[5], -9 c[1] + c[3], c[1]} In[8]:= V[9] Out[8]= {0, c[1]...

... or a min- imum, whereas if the determinant is negative then in a neighbourhood of  a b  , f is a saddle point. If the determinant is zero, the test is uninforma- tive. “Proof” by arm-waving: ... diagonalisation. We simply note that the determinant in the first two cases is positive and the determinant is not changed by rotations, nor is the sign of the determinant changed by scalin...
