Research Activities

Studying walls and shells in cosmology, specially in brane cosmological models, by the W. Israel formalism. Also studying the effect of finite thickness for the wall and comparing the zero-thickness limit with the previous for thin wall approximations, in 3+1 dimensions and extension to 4+1 dimensions.

Present Research Project at IPM

Thick Walls and Shells in Cosmology
