%0 Journal Article %T Wiener integral for the coordinate process under the $ ¦Ò$-finite measure unifying Brownian penalisations %A Kouji Yano %J Mathematics %D 2009 %I arXiv %X Wiener integral for the coordinate process is defined under the $ \sigma $-finite measure unifying Brownian penalisations, which has been introduced by Najnudel, Roynette and Yor. Its decomposition before and after last exit time from 0 is studied. This study prepares for the author's recent study of Cameron--Martin formula for the $ \sigma $-finite measure. %U http://arxiv.org/abs/0909.5130v2
