Continuing A.E. van Vogt's World of Null-A In this heart-stopping sequel to A.E. van Vogt's World of Null-A, Gilbert Gosseyn, the superhuman amnesiac with a double brain, must pit his wits once more against the remorseless galactic dictator Enro the Red and the mysterious shadow-being known as The Follower. And he must do it while he is being hurled headlong through unimaginable distances in space, in time, and through alternate eternities to fend off the death and complete the rebirth of the Universe itself! At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Contact has been made between other planets and Gilbert Gosseyn finds himself trying to stop a galactic war between Earth and Venus.

This exploration of a notorious mathematical problem is the work of the man who discovered the solution. Written by an award-winning professor at Stanford University, it employs intuitive explanations as well as detailed mathematical proofs in a self-contained treatment. This unique text and reference is suitable for students and professionals. 1966 edition. Copyright renewed 1994.

Concise classic by great mathematician and physicist deals with logic and mathematics of set and function, concept of number and the continuum. Bibliography. Originally published 1918.

In this sequel to World of Null-A, Gilbert Gosseyn must learn to use both hisbrains and function in various bodies in order to save the universe from Enrothe Red.

In this book, the authors describe a continuum limit of the Toda ODE system, obtained by taking as initial data for the finite lattice successively finer discretizations of two smooth functions. Using the integrability of the finite Toda lattice, the authors adapt the method introduced by Lax and Levermore for the study of the small dispersion limit of the Korteweg de Vries equations to the case of the Toda lattice. A general class of initial data is considered which permits, in particular, the formation of shocks. A feature of the analysis in this book is an extensive use of techniques from the theory of Riemann-Hilbert problems.

A lucid, elegant, and complete survey of set theory, this three-part treatment explores axiomatic set theory, the consistency of the continuum hypothesis, and forcing and independence results. 1996 edition.
