Spencer J. Bloch has had a substantial impact on, in particular, algebraic K-theory, algebraic cycles and motives. This conference will serve as a tribute to part of his work, concentrating on motives and algebraic cycles. Some of the speakers will discuss Bloch's work in those areas, most will talk about recent developments in those or related fields.
