Enlargement of Filtration with Finance in View

“This book presents a succinct exposition on the theory of filtration enlargements. … The book delivers a systematic and updated account of the subject. There is a long list of papers in the references, including the authors’ own contributions, providing a broad perspective. … it is an excellent guide from which the reader will gain a global view of the field.” (Erick Treviño-Aguilar, Mathematical Reviews, August, 2018)​“The book is devoted to enlargement of filtration – an important tool and field of study in the theory of stochastic processes. … The book is a useful reading for students and professionals in theory and practice of finance.” (Pavel Stoynov, zbMATH 1397.91003, 2018)
