We test two methods to estimate a partition function of a system consisting of multi-atom molecules with intermolecular … (bovine pancreatic trypsin inhibitor) would be moving is limited, so by making a correction to a partition function of a rigid … oscillators. We obtain the partition function for the oscillators within a harmonic approximation. The function also depends on …

We present a new method based on genetic algorithms which permits to determine efficiently the partition function and … eigenfunctions for a given Hamiltonian, while the partition function attains its global extremum (maximum) for a given temperature …. We calculate the spectrum and the partition function in the case of few interacting particles in one-dimensional infinite …

one of its ends to the point where the potential changes. For this model, the exact partition function is available. In …

We exhibit the partition function of the zero-dimensional λϕ4 model as a simple exact expression in terms of the … plane λ, for |argλ|<π. Consequently, the partition function understood as an analytic continuation is defined for all values …-vanishing imaginary part. We also evaluate the partition function on perturbative grounds, using the Borel summation technique and we …

We consider partition function games and introduce new defini-tions of the core that include the effects of … with fewer players and with a partition function that captures the externalities of the deviating coalition. Some …

per-member partition function satisfying the conditions of Yi [17] to include negative externalities. The solution gives …

The distribution of the zeros of the partition function in the complex temperature plane (Fisher zeros) of the two …
