“…Thus a GBMP is determined by the continuous functions a(t) and b(t). The function space C a,b [0, T ], induced by GBMP, was introduced by Yeh [26,27] and was used extensively in [6,7,8,9,10,11,12,13,14]. The function space C a,b [0, T ] used in [6,7,8,9,10,11,12,13,14] can be considered as the space of sample paths of the GBMP.…”
