Hence C(K,G)=\operatorname{map}(K,G), i.e., the compact-open topology is the topology of the internal mapping space in the category {\mathbf {T}} of compactly generated spaces.We let \hom (K,G) denote the set of continuous homomorphisms with the subspace topology of \operatorname{map}(K,G). Since \operatorname{map}(K,G...

Since O is open and (k,\beta (k))\in O, there are open subsets U_k\subset K and V_k\subset G with(k,\beta (k))\ \subseteq \ U_k\times V_k \ \subseteq \ O \ .Since \beta is continuous, the set \beta ^{-1}(V_k) is open in K, hence so is U_k\cap \beta ^{-1}(V_k); moreover, k\in U_k\cap \beta ^{-1}(V_k).

We start out by checking that taking fixed points commutes with certain kinds of colimits, namely pushouts and sequential colimi...

Since X is weak Hausdorff, the diagonal \Delta _X is closed in X\times X. So G\times \Delta _X is closed in G\times X\times X. The orbit relation E is the image of G\times \Delta _X under the above composite, so E is closed in X\times X.(ii) If O is an open subset of X, then g O is open for every g\in G, since left tra...

If (x,t)\in F(l_+)\times K^l is of minimal dimension in its equivalence class, then x is non-degenerate and t\in C_l(K), for otherwise (x,t) would be equivalent to an element of smaller dimension. So (\operatorname{Id},\operatorname{Id},t,x) is a reduction datum for (x,t), and hence \rho (x,t)=[x,t]. Now we let (y,s) b...

Source and target of h/k are cofibrant as G-spaces, so this G-weak equivalence is even a G-homotopy equivalence. The upper row in the commutative diagram of G-spaces@C=18mm{ F(|A|)[r]^-{F(|i|)} [d]_{F(k)}^\simeq & F(|B|)[r]^-{F(|q|)} [d]_{F(h)}^\simeq & F(|B/A|) [d]^{F(h/k)}_\simeq \\ F(X) [r]_-{F(j)} & F(Y)[r]_-{F(p)}...

This completes the proof that the sequence (REF ) is a G-homotopy fiber sequence.Now we treat a general homotopy cocartesian square of finite based G-CW-complexes:{ X[r]^-j[d]_k & Y[d]^h \\ Z [r]_i & P}By replacing Y and P by the reduced mapping cylinders of j respectively i, we may assume that the horizontal maps are ...

The previous paragraph shows that the map\tilde{\alpha }\ : \ F^{G^\circ }(X^{G^\circ })\ \longrightarrow \ \operatorname{map}_*(S^V,F^{G^\circ }(X^{G^\circ }\wedge S^V))induces a weak equivalence on \bar{G}-fixed points. Proposition REF provides a homeomorphism( F^{G^\circ }( X^{G^\circ }) )^{\bar{G}}\ \cong \ (F(X)^{...

Moreover, for every subgroup H of G the space( F_{S^1}(1_+))^H\ \cong \ F(S^1)^His path connected by Proposition REF  (i). So the abelian monoid \pi _0( F_{S^1}(1_+)^H) has only one element, and is thus an abelian group. Hence F_{S^1} is very special.So Theorem REF applies to the G-cofibrant and very special {\mathbf {...
