String with deformed dispersion relation

Abstract We study string theory with momentum living on de Sitter space. We argue that consistency of the theory implies that the global momentum can be defined on de Sitter space. Then we perform careful canonical analysis and we we also show that this presumption leads to the string with deformed dispersion relation.
