Palatini formulation of modified gravity with a nonminimal curvature-matter coupling

Palatini versus metric formulation in higher-curvature gravity

We compare the metric and the Palatini formalism to obtain the Einstein equations in the presence of higher-order curvature corrections that consist of contractions of the Riemann tensor, but not of its derivatives. We find that, with the exception of standard Einsteingravity, the two formalisms are not equivalent, but that the Palatini formalism is contained within the metric formalism, in the...

the trace of translators ideology in literary translations: a case study of persian translation of the scaret letter

رساله ی حاضر تلاشی است برای بررسی مبحث ایدئولوژی در ترجمه ادبی و تاثیرات آن بر کار مترجم، اعم از گزینش واژگان و ساختارهای دستوری؛ با تمرکز بر تحلیل انتقادی گفتمان در متن مبدأ و متن مقصد، که در این رساله متن مبدأ رمان داغ ننگ اثر ناتانیل هاوثورن و ترجمه فارسی سیمین دانشور به عنوان متن مقصد مورد بررسی قرار گرفته است. تجزیه و تحلیل رمان های مورد نظر به طور عمده بر اساس مدل پیشنهادی فرحزاد(2007) بر...

Hybrid Metric-Palatini Gravity

Recently, the phenomenology of f(R) gravity has been scrutinized. This scrutiny has been motivated by the possibility to account for the self-accelerated cosmic expansion without invoking dark energy sources. Besides, this kind of modified gravity is capable of addressing the dynamics of several self-gravitating systems alternatively to the presence of dark matter. It has been established that ...
