THEORETICAL MODELS OF DARK ENERGY [PDF]
International Journal of Modern Physics D, 2012 Mounting observational data confirm that about 73% of the energy density consists of dark energy which is responsible for the current accelerated expansion of the Universe. We present observational evidences and dark energy projects. We then review various theoretical ideas that have been proposed to explain the origin of dark energy; they contain the ...

Theoretical Models for Neutrino Masses [PDF]
, 2012 The recent measurements of the neutrino reactor angle require a re-examination of flavour models based on discrete groups. Indeed, when these models deal with the Tri-Bimaximal, the Bimaximal and the Golden Ratio mixing patterns, some tensions arise in ...

The nature of voids – I. Watershed void finders and their connection with theoretical models [PDF]
, 2015 The statistical study of voids in the matter distribution promises to be an important tool for precision cosmology, but there are known discrepancies between theoretical models of voids and the voids actually found in large simulations or galaxy surveys.

Theoretical Limitations of Self-Attention in Neural Sequence Models [PDF]
Transactions of the Association for Computational Linguistics, 2019 Transformers are emerging as the new workhorse of NLP, showing great success across tasks. Unlike LSTMs, transformers process input sequences entirely through self-attention.

Scaling properties of the redshift power spectrum: theoretical models [PDF]
, 2000 We report the results of an analysis of the redshift power spectrum $P^S(k,\mu)$ in three typical Cold Dark Matter (CDM) cosmological models, where $\mu$ is the cosine of the angle between the wave vector and the line-of-sight.

, 2021 Game theory is a tool to model and discover social mechanisms. The aim of this chapter is to show how the tool can be used by engaging the reader's interest in the game-theoretic modelling of social dilemmas. Social dilemmas are situations in which several agents face a decision conflict because of their interdependence.
