    In this thesis, inflationary phase of the universe in the framework of generalized Chaplygin gas is studied. We consider modified cosmological scenarios based on two entropy corrections known as Tsallis and Barrow entropy which lead to the modification of Friedmann equations. Using these correction and modified equations, we discuss the slow roll parame ters, number of e-folds, curvature perturbation, tensor to scalar ratio and spectral index. To analyze the effects of these entropy corrections on infla tionary dynamics, we plot the graphs of tensor to scalar ratio and spectral index for two different scalar potentials. We observe the variations in the values of these inflationary parameters with respect to Tsallis and Barrow parameters. The graphical analysis demonstrates the compatibility of our models with the Planck data from 2020. Moreover, in view of these correc tions to entropy, we also find out the bounds of swampland conjecture for generalized Chaplygin gas. In all the cases, this bound remains less than one which is according to observational data

    Study of Entropy Corrected Cosmic Scalar Field Inflation
    (Library Information Services, COMSATS University Islamabad, Lahore Campus., 2017-11-20) Rimsha; LHR TP 8726
    The purpose of this study is to identify the effect of consumer oriented variables (price consciousness, value consciousness, perceived store image, past experience and fashion involvement) on purchase intentions of females towards prêt branded clothes. The survey method by using random sampling technique was used to collect the data from the females of Lahore. Data analysis were conducted by using bivariate correlation and multiple regression analysis. The findings of the result explored that perceived store image, past experience and fashion involvement are the three significant variables that enhances the purchase intentions of females towards prêt. While price consciousness has inverse relation with the purchase intention. This is the first empirical study in order to understand the purchase intentions of females towards prêt branded clothes in Pakistan and provides significant result to understand the importance of consumer oriented variables in purchase intentions towards prêt.
