Talk:Bipolar theorem

The statement of the bipolar theorem on this page does not agree with the statement on https://en.wikipedia.org/wiki/Polar_set, where the bipolar is not asserted to be a cone as it is here. This article does not actually give a definition of polar set, so that might be the root of the problem. 2607:F010:2E9:19:A445:F65:A8EC:576A (talk) 15:29, 11 September 2018 (UTC)
