Abstract

Telah dibangun model kosmologi brane dengan parameter perlambatan ekspansi yang gayut linear terhadap waktu. Dalam model ini telah diturunkan persaman untuk evolusi faktor skala, parameter Hubble, kerapatan materi-energi dan tekanan alam semesta.   Pada limit energi rendah seperti pada era alam semesta sekarang ini, yaitu pada saat rapat materi-energi jauh lebih kecil dibandingkan dengan tegangan brane, model yang di bangun ini akan kembali ke model Akarsu-Dereli.
