... 5th rows; the same argument is repeated one more round, then it’s clear it won’t work. 16 1x3s would work: Fill the 3-cell col with a single 1x3, with the rest covered by horizontal 1x3s. Now prove that 24 1x2s won’t work: Suppose it did. Among all such coverings there would be one minimizing the nu ...

Most rank two finite groups act freely on a homotopy product of two
... Now we will look at the prime two. We begin with a restatement of Proposition 7.1 of Alperin, Brauer, and Gorenstein, ”Finite simple groups of 2-rank two”. Theorem 13 (Alperin, Brauer, and Gorenstein) Let G be a finite group such that rk2(G) = 2 and let G2 ∈ Syl2(G). If Ω1(Z(G2)) is not strongly cl ...

... would have to cross the x axis somewhere between 1 and 5. This is the Intermediate Value Theorem in action. We can see that since Descartes Rule told us there was 1 positive real zero, that is must be between 1 f(1) = -9 and 5 so you wouldn’t try 1/2, but you'd try 5/2 instead. ...

... A schematic representation of a sequence of operations, as in a manufacturing process or computer program. It is a graphic representation of how a process works, showing, at a minimum, the sequence of steps. A flowchart consists of a sequence of instructions linked together by arrows to show the ...

... (1) If F is any functor from C to the category of sets, the natural transformations between hX and F are in natural correspondence with the elements of F (X). (2) h is an equivalence of categories with a full subcategory of Hom(C ◦ , D). Proof. Given a natural transformation α : hX −→ F, we assign ...
