Local Rank-One Logarithmic Instability for the Mixed Hessian of the Dispersionless Toda $τ$ -Function

Oleg Alekseev

We study a weighted renormalization of the mixed Hessian of the dispersionless Toda $τ$ -function associated with polynomial conformal maps. The starting point is an explicit logari…

Spectral Structure of the Mixed Hessian of the Dispersionless Toda $τ$ -Function

Oleg Alekseev

We study the mixed Hessian of the dispersionless Toda $τ$ -function for the one-harmonic $s$ -fold symmetric conformal map $f (w) = r w + a w^{1 - s}$ . This Hessian is the susceptibility matr…

Variational Pattern Selection

Mark Mineev-Weinstein, Oleg Alekseev

We address pattern selection problems in nonlinear interface dynamics by maximizing the entropy of the most probable (classical) scenario associated with the processes. This variat…

Universality of stochastic Laplacian growth

Oleg Alekseev

We consider a stochastic Laplacian growth problem in the framework of normal random matrices. In the large $N$ limit the support of eigenvalues of random matrices is a planar domai…
