What constitutes the 'tiyomet' (double leaf) whose splitting invalidates a lulav, and how much must be split?
Synopsis
Major dispute between the Mechaber (following Rif/Rambam: tiyomet = all double leaves, invalid when majority split in majority of their length) and the Rema (following rishonim who hold the tiyomet = the central upper leaf, invalid if split down to the spine). Further dispute on whether even partial splitting of the upper leaf is a concern.
