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…
