| Abstract: | We consider the family of logics from NExt(KTB) which are determined by linear frames with reflexive and symmetric relation of accessibility. The condition of linearity in such frames was first defined in the paper 9]. We prove that the cardinality of the logics under consideration is uncountably infinite. |
