“Enumeration Degree and Existential Atomicity”
We will investigate the notion of a Turing degree of a structure. However, since it is not as useful as we would hope, we instead use enumeration degrees, which prove more fruitful. We then establish some results concerning existential atomicity of a structure.

“Second Variation Formula, Morse Index and Stability”
We will derive the Second variation formula for a minimal submanifold. After defining the Morse index and Stable Minimal Submanifolds, we will derive the Stability Inequality. As a result, we will prove a theorem due to Simons and another theorem due to Schoen and Yau.

"Two and a half examples"
After some review and a useful exercise on locally ringed spaces, we will look at three important examples. Affine plane minus the origin, affine line with doubled origin and the projective line. (We have seen the first example already, hence the half in the title.) We will show that all of these are schemes that are not affine.

“The Lie Algebra of an Algebraic Group”
We will introduce the Lie Algebra of a linear algebraic group and begin studying the adjoint representation.

"Topos theory XIII"
We continue chapter 8 of Goldblatt; we continue the study of Heyting algebras, and, time permitting, Kripke semantics.

"Continuous model theory VII"
We begin chapter 7 of Model theory for metric structures; we discuss continuous analogues of saturation and homogeneity.
