.... The question dates back to Hermite in [21] where he suggests finding a generalization of the continued fraction algorithm which reflects the algebraic nature of the parameter(s) As a response to this problem Jacobi developed a special case of what is now called the Jacobi Perron algorithm (see [6, 32, 37]) Since then, a number of other multidimensional division algorithms have been studied including [2, 5, 8, 10, 18, 19, 24, 25, 26, 28, 29, 33, 43, 44] to name just a few. See [9, 38, 39] for nice surveys on multidimensional continued fractions) It is known that for each n tuple of irrationals ....

....get regular, i.e. usual continued fractions by special substitutions. However, a systematic mechanical method for expressing a given semi regular continued fraction via a regular one was first developed by Minkowski (cf. 43] pp. 116 118) and was further elucidated in Perron s classical book [50], Kap. V, x40. In fact, in order to write down (3.1) as a regular continued fraction, one has to define 0 : 1; 1, to add a 1 1 Delta Delta Delta in front of every negative i , to replace all minus signs by plus signs, and finally to substitute a i Gamma 1 2 ( 1 Gamma i Gamma1 ) ....

....Diophantine approximation problem of n rationals w.r.t. the norm fA . It is known for a long time that the two dimensional simultaneous Diophantine approximation problem (n=1) can be solved in polynomial time by the method of continued fractions as described in Khintchine [Khi56] Perron [Per13] and Grotschel, Lov asz and Schrijver [GLS88] Moreover, in the twodimensional case best approximations have a nice geometric structure.

....this recurrence, we obtain a finite continued fraction that looks like A h 1 (z) z 1 z 1 z 1. 9.48) The general theory of continued functions represents a convergent as a quotient of two sequences satisfying recurrences involving the partial quotients. For references, see [218, 319]. After playing with this idea, one finds that the substitution A h (z) zP h (z) P h 1 (z) 9.49) gives P h 1 (z) P h (z) zP h 1 (z) h # 2 , where P 0 (z) 0, P 1 (z) 1. This is a linear recurrence when we regard z as fixed, and so the theory presented before leads to the ....

....recurrence 44 d n = a n,n d n 1 a n,n 1 a n 1,n d n 2 . A three term recurrence occurs, for instance, in the theory of continued fractions and of orthogonal polynomials, which can hence be expressed as determinants, e.g. the continuant corresponding to a continued fraction (cf. [77], p. 11) is a determinant of a matrix H # n (with 1 s on the upper side diagonal) A very useful property of a sequence (P n ) n of orthogonal polynomials is that their eigenvalues interlace. This extends to Hermitian Hessenberg matrices. For a recent result on interlacing properties in the ....
