introduction



basic notions

  • dimer configurations
  • set of dimer configurations
  • partition function
  • Kasteleyn matrix
  • height function
  • spectral curve
  • surface tension



Termperley equivalence

  • spanning trees on \gamma rooted at x
  • dimers on D(\gamma)



Domino tiling and height function

  • bipartite graph



energy and weight systems

  • define a weight function on the edges of the graph \gamma\(w:E(\Gamma)\to \mathbb{R}_{\geq 0}\)
  • For a dimer configuration D,\(w(D)=\prod_{e\in D} w(e)\)
  • energy function\(\epsilon:E(\Gamma)\to \mathbb{R}\)
  • For a dimer configuration D,\(\epsilon(D)=\sum_{e\in D} \epsilon(e)\)
  • energy and weight function\(w(e)=\exp (-\frac{\epsilon(e)}{T})\)
  • partition function\(Z_{\Gamma}=\sum_{D\subset \Gamma} \prod_{e\in D} w(e)\)



fH

  • P(z_1,z_2,w) if weights are positive real., then P=0 is a Harnack curve of genus
  • g=|int(N)|
  • P(z_0,z_2)=0 is harnack if the amoeba map is at most 2-to-1.
