... Let M1 and M2 be a pair of manifolds-with-boundary and suppose that ∂M1 is homeomorphic to ∂M2 . Let f : ∂M1 → ∂M2 be a homeomorphism and set X := M1 ∪ M2 . Let P be the partition of X consisting of all single sets {x} where x ∈ X − (∂M1 ∪ ∂M2 ) and all sets of the form {x, f (x)} where x ∈ ∂M1 . T ...

... According to Schoenfeld (1986), most students who have had a year of high school geometry are "naive empiricists." Similarly, Fischbein and Kedem (1982) found that high school students, after finding or learning a correct proof for a statement, still maintained that surprises were possible and that ...

... then α ∗ β is homotopic to γ ∗ δ. 3. Suppose that a topological space X has a function m : X × X → X. Show that if α and β are any paths in X, the definition (α · β)(t) = m(α(t), β(t)) is homotopy invariant, in the sense that [α] ∗ [β] = [α ∗ β] is well-defined on homotopy classes of paths. 4. Show ...

This assignment is of course related to the first one, as the non-Euclidean geometries considered are exactly those (two-dimensional) geometries violating the parallel postulate while retaining all the other Euclidean pos ...
