We translate Brown's criterion for homological finiteness properties to the setting of Bredon homology.
Localisation and Completion with an addendum on the use of Brown-Peterson homology in stable homotopy
Localisation Completion addendum
2011/2/25
In spring 1973 Frank Adams gave a course at the University of Chicago on localisation and completion. This was in the very early days of the subject,which arose from disparate constructions of Quillen...
Brown representability often fails for homotopy categories of complexes
Brown representability Adjoint functor Triangulated cate-gory
2011/2/22
We show that for the homotopy category K(Ab) of com-plexes of abelian groups, both Brown representability and Brown repre-sentability for the dual fail. We also provide an example of a localizing subc...
应用Brown运动在Holder范数下的大偏差和小偏差得到了Brown运动连续模在Holder范数下的泛函极限的收敛速率.

双分式Brown运动的自相交局部时和相遇局部时
双分式Brown运动 自相交局部时 相遇局部时 强局部不确定性
2009/8/31
考虑一个双分式Brown运动的局部时、自相交局部时和两个独立的双分式Brown运动的相遇局部时问题. 通过双分式Brown运动的强局部不确定性、$L^2$收敛和混沌展开, 验证自相交局部时和相遇局部时的存在性和光滑性.
Brown定理的一个组合证明

设X=(X_t)_(t≥0)为R~d中的标准Brown运动,B_r={x:x∈R~d,|x|Br,首出Br及停留在Br中的时间.本文给出了求这些变量的矩的一般公式,并求出了前二阶矩.
对于暂留Browm运动，我们给出了极大游程与极小游程的若干定义，并且求出了 极大游程（极小游程）的分布，以及极大游程（极小游程）与首达极大时（首达极小时）的联 合分布．作为推论求出了首达极大时与首达极小时的分布．
