%0 Journal Article %T Jacob's ladders and the tangent law for short parts of the Hardy-Littlewood integral %A Jan Moser %J Mathematics %D 2009 %I arXiv %X The elementary geometric properties of the Jacob's ladders \cite{7} lead to a class of new formulae for short parts of the Hardy-Littlewood integral. This class of formulae cannot be obtained by methods of Balasubramanian, Heath-Brown and Ivic. %U http://arxiv.org/abs/0906.0659v3
