摘要

我们定义了一个 SLn(Z)\operatorname{SL}_n(\mathbb{Z})-不变的凸域热力学齐次函数。其二维情形可表述为边界Dirichlet级数表示,求和项由Farey配对索引化。对于 C3C^3 严格凸域,该函数可在 (s)>3/5\Re(s)>3/5 延拓为全纯函数,除 s=2/3s=2/3 处有一个简洞极点,其残数与等仿射周长成比例。通过Tauberian论证,可得当 t0t\rightarrow 0 时,t1/3t^{1/3} 波前晶格-周长渐近形式。

备注

87 pages, 9 figures. Main theorem: for smooth strictly convex planar domains, the tropical zeta function continues meromorphically to Re(s)>3/5 with simple pole at s=2/3; residue gives equiaffine perimeter. Includes Tauberian asymptotic for lattice perimeter of tropical wave fronts
