Title：Basic properties of solid abelian groups
Abstract：In the previous lecture, we have seen the definition of solid abelian groups. In this lecture, we will firstly focus on the formal properties of the category of solid abelian groups i.e. Thm 3.2.3 (1)-(8) except(4). Then we will give explicit computations of (derived) solidification of real number R, P and Z[S] when S is a light profinite set and the (derived) solid tensor of countable product of Z with itself , which will give the remaining part of Thm 3.2.3 except (14). Finally, we will present a computation of derived solidification of Z[X] when X is a CW complex.
