A MELLIN SPACE APPROACH TO COSMOLOGICAL CORRELATORS

Abstract We propose a turbosound ts-18sw700/8a Mellin space approach to the evaluation of late-time momentum-space correlation functions of quantum fields in (d + 1)-dimensional de Sitter space.The Mellin-Barnes representation makes manifest the analytic structure of late-time correlators and, more generally, provides a convenient general d framewo

Test-time adaptation (TTA) aims to optimize source-pretrained model parameters to target domains using only unlabeled test data.However, traditional TTA methods simply southern cat shirt often risk overfitting to the specific, localized test domains, leading to compromised generalization.Moreover, these methods generally presume static target domai
