%0 Journal Article %A Acquistapace, Francesca %A Broglia, Fabrizio %A Ruiz Sancho, Jesús María %T On the Pythagoras numbers of real analytic curves. %D 2007 %@ 0025-5874 %U https://hdl.handle.net/20.500.14352/49899 %X We show that the Pythagoras number of a real analytic curve is the supremum of the Pythagoras numbers of its singularities, or that supremum plus 1. This includes cases when the Pythagoras number is infinite. %~
