Özet
Bu çalışmada, homojen izotropik FRW evreni için karanlık enerji adaylarından k-essence, Tachyon ve Quintessence gibi madde dağılımları Lyra geometri çerçevesinde araştırıldı. Lyra geometrideki alan denklemlerinin tam çözümleri elde edebilmek için 3 farklı frenleme parametresi kullanarak 3 ayrı evren modeli oluşturuldu. Her bir evren modeli için elde edilen niceliklerin grafikleri çizildi ve detaylı olarak irdelendi.
In this study, the distribution of matter such as k-essence, tachyon and quintessence, which are among the dark energy candidates for the homogenous isotropic FRW universe, were investigated within the framework of Lyra geometry. In order to obtain exact solutions of the field equations in the Lyra geometry, 3 separate universe model was created using 3 different decerelation parameters. Graphs of quantities obtained for each universe model were drawn and examined in detail.
