Lattice model may refer to:

  • Lattice model (finance), a "discrete-time" model of the varying price over time of the underlying financial instrument, during the life of the insturment.
  • Lattice model (biophysics), one-dimensional lattice models are widely used for the description of biological polymers, such DNA and actin, while two-dimensional lattice models are used for protein binding to the lipid membrane. The general concept is to divide the system into the elementary units that are associated with different states (e.g. bound/unbound). The states of the whole system are then calculated as different combinations of states of elementary units. The elementary DNA units are usually taken as nucleotides A, T, C and G. Other choices of the elementary lattice unit are also possible. Several methods of constructing lattice models of DNA-protein binding have been developed in the past. They may be roughly divided into four classes: combinatorial methods, generating functions, recurrent relations and the transfer-matrix method.[1]
