  2. Partition function (statistical mechanics) - Wikipedia

    en.wikipedia.org/wiki/Partition_function...

    The partition function is a function of the temperature T and the microstate energies E 1, E 2, E 3, etc. The microstate energies are determined by other thermodynamic variables, such as the number of particles and the volume, as well as microscopic quantities like the mass of the constituent particles.

  3. Transfer-matrix method (statistical mechanics) - Wikipedia

    en.wikipedia.org/wiki/Transfer-matrix_method...

    In either case, the partition function may be solved exactly using eigenanalysis. If the matrices are all the same matrix W , the partition function may be approximated as the N th power of the largest eigenvalue of W , since the trace is the sum of the eigenvalues and the eigenvalues of the product of two diagonal matrices equals the product ...

  4. Partition function (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Partition_function...

    The partition function or configuration integral, as used in probability theory, information theory and dynamical systems, is a generalization of the definition of a partition function in statistical mechanics. It is a special case of a normalizing constant in probability theory, for the Boltzmann distribution.

  5. Partition function (number theory) - Wikipedia

    en.wikipedia.org/wiki/Partition_function_(number...

    A partition in which no part occurs more than once is called strict, or is said to be a partition into distinct parts. The function q(n) gives the number of these strict partitions of the given sum n. For example, q(3) = 2 because the partitions 3 and 1 + 2 are strict, while the third partition 1 + 1 + 1 of 3 has repeated parts.

  6. Newman's conjecture - Wikipedia

    en.wikipedia.org/wiki/Newman's_conjecture

    In mathematics, specifically in number theory, Newman's conjecture is a conjecture about the behavior of the partition function modulo any integer. Specifically, it states that for any integers m and r such that , the value of the partition function () satisfies the congruence () for infinitely many non-negative integers n.

  7. Ensemble (mathematical physics) - Wikipedia

    en.wikipedia.org/wiki/Ensemble_(mathematical...

    While this would solve the problem, the resulting integral over phase space would be tedious to perform due to its unusual boundary shape. (In this case, the factor C introduced above would be set to C = 1 , and the integral would be restricted to the selected subregion of phase space.)

  8. Partition problem - Wikipedia

    en.wikipedia.org/wiki/Partition_problem

    The partition problem is a special case of two related problems: In the subset sum problem, the goal is to find a subset of S whose sum is a certain target number T given as input (the partition problem is the special case in which T is half the sum of S).

  9. Polymer field theory - Wikipedia

    en.wikipedia.org/wiki/Polymer_field_theory

    A polymer field theory is a statistical field theory describing the statistical behavior of a neutral or charged polymer system. It can be derived by transforming the partition function from its standard many-dimensional integral representation over the particle degrees of freedom in a functional integral representation over an auxiliary field function, using either the Hubbard–Stratonovich ...
