These concern the structure of free resolutions associated with a very ample line bundle on a projective variety. There are interesting conjectures and ideas related to the structure of free resolutions and the intrinsic geometry connected with properties N_p and M_p. A lot of attention has been paid of property N_p, not so much for property M_p. In this talk we will describe some new results about properties M_p for an algebraic surface, some higher dimensional varieties, and even interesting everywhere non reduced schemes called carpets.
