文摘We study the periodic cosmic transit behavior of the accelerated universe in the framework of symmetric teleparallelism. The exact solution of field equations is obtained by employing a wellknown deceleration parameter(DP) called periodic varying DP, q =m coskt-1. The viability and physical reliability of the DP are studied by using observational constraints. The dynamics of periodicity and singularity are addressed in detail with respect to time and redshift parameter.Several energy conditions are discussed in this setting.
