| Abstract: | The iteration formula for the partition functions of the ladder frustrated Ising model is derived and the thermodynamical properties of three models at low temperature is studied.It is found that when the temperature tends to zero,the thermodynamical quantities show discontinuities at some values of parameter.Their ground state configurations at the different parameter regions and the reasons of singularity are analysed. |
