At the summer time tuition Saint Petersburg 2001, the most lecture classes bore on fresh development in asymptotic illustration idea: these written up for this quantity take care of the speculation of representations of limitless symmetric teams, and teams of endless matrices over finite fields; Riemann-Hilbert challenge options utilized to the learn of spectra of random matrices and asymptotics of younger diagrams with Plancherel degree; the corresponding valuable restrict theorems; the combinatorics of modular curves and random timber with software to QFT; unfastened chance and random matrices, and Hecke algebras.

What converges and survives in the limit are the moments of the random matrices. Research supported by a grant of NSERC, Canada A. M. ), pp. 53–73, 2003. c Springer-Verlag Berlin Heidelberg 2003 54 R. Speicher To talk about moments we need in addition to the random matrices also a state. e. for A = (aij )N i,j=1 we have trN (A) := 1 N N aii . e. for A = (aij (ω))N i,j=1 (where the entries aij are random variables on some probability space Ω equipped with a probability measure P ) we have trN ⊗ E(A) := 1 N N aii (ω)dP (ω).

The critical region is around n ∼ 2 λ ∼ 2 N . Poissonization helps because of the following wonderful (1) fact: there is an exact formula for φn (λ) −λ φ(1) Dn−1 e2 n (λ) = e √ λ cos θ = e−λ Dn−1 (λ) Dn−1 is the n × n Toeplitz determinant with weight function f (eiθ ) = √ 2 λ cos θ , e π Dn−1 (f ) = det ckj = ck −j = e−i(k−j)θ f (eiθ ) −π dθ 2π 0≤k,j≤n−1 This formula was ﬁrst found by Gessel (1990), but has since been discovered independently by many authors: Johansson, Diaconis–Shahshahani, Gessel– Weinstein–Wilf, Odylyzsko, Poonen, Widom, Wilf, Rains, Baik, Deift and Johansson (1999) also give a new proof.

If the shuﬄed deck is in a “permutation state” π, we let pN (π) denote the number of piles one obtains by playing patience sorting starting from π and using the greedy strategy. For example, suppose N = 6 cards are in the order 4 1 3 5 6 2 (corresponding to the permutation π(1) = 4, π(2) = 1, . . ). Then the game proceeds as follows: 11 1 1 12 4 4 43 435 4356 4356 and p6 (π) = 4. Question: Putting uniform distribution on the set of shuﬄes {π ∈ SN }, SN = symmetric group, how does pN (π) behave as N → ∞?
