Columbia Shiur: Shitas HaRambam, Ramban, Ritvah, about the Aseih of Tishbos. Is there a separate Isur Deoraisa for עמל וטרחה on Shabbos. What about עושה שבת חול? Are these two separate ideas? What is the relationship the Deoraisa dimension of Shvus and the Derabanan? Is the Rambam's model similar to that of the Ritva and Ramban?
