Multifractional brownian motion and entropy
http://www.apsipa.org/proceedings/2024/pdfs/0000189.pdf WebBrownian motion is a semimartingale when it is of the special form MH,a := B + aBH, where B is a Brownian motion, BH an independent fractional Brownian motion and aE R\{O}. To avoid localization arguments we consider (MtHa)tE[O,T] for T < oc. It follows from self-similarity of fractional Brownian motion that the process (Bt + aBH) tE[0,T]
