семинар кафедры ФВЭиЭЧ 18.10.16



Дорогие коллеги,

в следующий вторник, 18 октября, в 12:45 состоится семинар кафедры
физики высоких энергий и элементарных частиц

Алексей Головнев

Конформные и дисформные соотношения в расширенных теориях гравитации.

Conformal and disformal relations between metrics are very important
for modern scalar-tensor models. As a somewhat non-trivial example, the
so-called mimetic gravity can be understood from the viewpoint of
(non)invariance under disformal transformations. On the other hand,
recently the concept of those relations was generalised to
curvature-dependent (instead of scalar-dependent) transformations in
disguise of C- and D-models. The latter might be nicely related to
non-local gravity models. In my talk, I will review some of these
topics.

В качестве ознакомительного материала по этой теме предлагаю следующие
статьи:

Nathalie Deruelle, Josephine Rua. Disformal Transformations, Veiled
General Relativity and Mimetic Gravity. https://arxiv.org/abs/1407.0825
Luca Amendola, Kari Enqvist, Tomi Koivisto. Unifying Einstein and
Palatini gravities. https://arxiv.org/abs/1010.4776
Alexey Golovnev, Tomi Koivisto, Marit Sandstad. Effectively nonlocal
metric-affine gravity. https://arxiv.org/abs/1509.06552

Всего хорошего,
Алексей Головнев.
