Resumen
WE RECONSIDER THE COSMOLOGICAL MODEL DISCUSSED BY SUNG-WON KIM IN THE CONTEXT OF FRIEDMANN-ROBERTSON-WALKER COSMOLOGIES WITH A TRAVERSABLE WORMHOLE, WHERE IT IS ASSUMED THAT THE MATTER CONTENT IS DIVIDED INTO TWO PARTS: THE COSMIC PART THAT DEPENDS ON TIME ONLY AND THE WORMHOLE PART THAT DEPENDS ON SPACE ONLY. THE COSMIC PART OBEYS THE BAROTROPIC EQUATION OF STATE
PC=??C. THE COMPLETE ANALYSIS REQUIRES FURTHER CARE AND REVEALS MORE INTERESTING RESULTS THAN WHAT WAS PREVIOUSLY SHOWN BY THE AUTHOR. THEY CAN BE READILY APPLIED TO THE EVOLUTION OF A LARGE CLASS OF COSMOLOGICAL MODELS WHICH ARE MORE GENERAL THAN FRIEDMANN-ROBERTSON-WALKER MODELS.
