Spectrum of the Metric Operator of a Simple Open image in new window-Symmetric Model



In papers (Krejčiřík D. et al.: J. Phys. A: Math. Gen.: 39(32), 10143–10153 (2006); Krejčiřík D., Tater M.: J. Phys. A: Math. Theor. 41(24), 244 (2008)) a new very simple Open image in new window-symmetric model was introduced and closed formula for the metric operator was found. We use an alternative integral form of this metric operator to study the spectrum of the metric.
