초록본문(Abstract) | Let M be a pointed metric, with a distinguished point 0. Denote Lip$_0$(M) the Banach space of Lipschitz functions on M that vanish at 0, and SNA(M) the subset of all such functions that strongly attain their norm (that is, they attain their biggest possible slope at some pair of points). In this talk we will discuss the linearity and the lineability of SNA(M) and its complement. In particular, we will show that these sets are never linear spaces, but they always contain infinite-dimensional Banach spaces. Several other related questions will also be discussed. This talk is based in a recent joint work with Geunsu Choi, Mingu Jung, and Han Ju Lee.
