For statement (i), one direction is true by definition: Any relation is the domain of its semicharacteristic function, and for a semidecidable relation, that function is an effectively calculable partial function. Conversely, for an effectively calculable partial function, f, we have the natural...

Definition 1. A smooth map 𝑃:(𝐵,𝑔𝐵)→(𝐹,𝑔𝐹) with 0≤𝑟𝑎𝑛𝑘(𝑃)=𝑝≤min{𝑟,𝑠} is said to be a Riemannian map at 𝑦∈𝐵 if the horizontal restriction 𝑃ℎ*𝑦:(𝑘𝑒𝑟(𝑃∗)𝑦)⊥→𝑟𝑎𝑛𝑔𝑒(𝑃∗)𝑦 (3) is a ...
Of course, we already proved (a stronger version) of this theorem already in Lecture 8, using the Perelman entropy, but this second proof is also important, because the reduced volume is a more localised quantity (due to the weight in its definition and so one can in fact establish local...

VELANI Strictly speaking, in the standard definition of Hausdorff measure the 0-cover by cubes is replaced by non-empty subsets in R k with diameter at most 0. It is easy to check that the resulting measure is comparable to 7-/s defined above, and thus the Hausdorff dimension is the ...
