The Wolf Prize, awarded by the Wolf Foundation in Israel, often goes to mathematicians who are in their sixties or older. That is to say, the Prize honours the achievements of a lifetime. T This valuable work features bibliographies, important papers, and speeches (for example at international congresses) of Wolf Prize winners, s uch as R. Bott, A.P. Calderon, A.N. Kolmogorov, M.G. Krein, P. Lax, H. Lewy, L. Lovasz, J. Milnor, J. Moser, I. Piatetski-Shapiro, J.P. Serre, C.L. Siegel, Y. Sinai, E.M. Stein, J. Tits, A. Weil, H. Whitney, A. Wiles and O. Zariski. This is the first time that documents on Wolf Prize winners have been published together. Since the work of the Wolf laureates covers a wide spectrum, much of the mathematics of the 20th century comes to life in this book Seminormal fine measures on Pk(lambda), Y. Abe; recursion theory and weak fragments of Peano arithmetic - a study of definable cuts, C.T. Chong and Y. Yang; lattice embedding into d-r.e. degrees preserving 0 and 1, D. Ding and L. Qian; on stationary reflection principles, Q. Feng; decidability and undecidability in the enumerable Turing degrees, S. Lempp; a note on weak segments of PFA, T. Miyamoto; linear set theory with strict comprehension, M. Shirahata; a solution to a problem of Marek and Truszcy ski, K. Su and H. Chen; DNK and natural reasoning, M. Yasugi and M. Nakata; Asian logic conferences, M. Yasugi; other papers
