Abstract. This is a complement to my previous article “Advanced Determinant Calculus ” (Séminaire Lotharingien Combin. 42 (1999), Article B42q, 67 pp.). In the present article, I share with the reader my experience of applying the methods described in the previous article in order to solve a particular problem from number theory (G. Almkvist, J. Petersson and the author, Experiment. Math. 12 (2003), 441– 456). Moreover, I add a list of determinant evaluations which I consider as interesting, which have been found since the appearance of the previous article, or which I failed to mention there, including several conjectures and open problems. 1.
The importance of Selberg integral

"... Abstract. It has been remarked that a fair measure of the impact of Atle Selberg’s work is the number of mathematical terms that bear his name. One of these is the Selberg integral, an ndimensional generalization of the Euler beta integral. We trace its sudden rise to prominence, initiated by a que ..."

Abstract. It has been remarked that a fair measure of the impact of Atle Selberg’s work is the number of mathematical terms that bear his name. One of these is the Selberg integral, an ndimensional generalization of the Euler beta integral. We trace its sudden rise to prominence, initiated by a question to Selberg from Enrico Bombieri, more than thirty years after its initial publication. In quick succession the Selberg integral was used to prove an outstanding conjecture in random matrix theory and cases of the Macdonald conjectures. It further initiated the study of qanalogues, which in turn enriched the Macdonald conjectures. We review these developments and proceed to exhibit the sustained prominence of the Selberg integral as evidenced by its central role in random matrix theory, Calogero–Sutherland quantum manybody systems, Knizhnik–Zamolodchikov equations, and multivariable orthogonal polynomial
Staircase Macdonald polynomials and the qDiscriminant, preprint: arXiv:0801.2443
"... We prove that a qdeformation Dk(X; q) of the powers of the discriminant is equal, up to a normalization, to a specialization of a Macdonald polynomial indexed by a staircase partition. We investigate the expansion of Dk(X; q) on different basis of symmetric functions. In particular, we show that it ..."

We prove that a qdeformation Dk(X; q) of the powers of the discriminant is equal, up to a normalization, to a specialization of a Macdonald polynomial indexed by a staircase partition. We investigate the expansion of Dk(X; q) on different basis of symmetric functions. In particular, we show that its expansion on the monomial basis can be explicitly described in terms of standard tableaux and we generalize a result of KingToumazetWybourne about the expansion of the qdiscriminant on the Schur basis. 1
Hyperdeterminantal computation for the Laughlin wave function
, 2008
"... The decomposition of the Laughlin wave function in the Slater orthogonal basis appears in the discussion on the secondquantized form of the Laughlin states and is straightforwardly equivalent to the decomposition of the even powers of the Vandermonde determinants in the Schur basis. Such a computat ..."

The decomposition of the Laughlin wave function in the Slater orthogonal basis appears in the discussion on the secondquantized form of the Laughlin states and is straightforwardly equivalent to the decomposition of the even powers of the Vandermonde determinants in the Schur basis. Such a computation is notoriously difficult and the coefficients of the expansion have not yet been interpreted. In our paper, we give an expression of these coefficients in terms of hyperdeterminants of sparse tensors. We use this result to construct an algorithm allowing to compute one coefficient of the development without computing the others. Thanks to a program in C, we performed the calculation for the square of the Vandermonde up to an alphabet of eleven lettres. 1

The initial purpose of the present paper is to provide a combinatorial proof of the minor summation formula of Pfaffians in [8] based on the lattice path method. The second aim is to study the applications of the minor summation formula to obtain several identities such as a variant of the Sundquist formula established in [31] about some extension of Pfaffian’s version of the Cauchy determinant, a simple proof of Kawanaka’s formula concerning a qseries identity involving Schur functions [15] (also, of the identity in [16] which is regarded as a determinant version of the previous one from our point of view). We also establish a certain identity similar to the Kawanaka formula.
