Seek and Ye Shall Find

This chapter proposes that search engines apply a verticalizing pressure on the WWW many-to-many information distribution model, forcing this to revert to a distributive model similar to that of the mass media. The argument for this starts with a critical descriptive examination of the history of search mechanisms for the Internet. Parallel to this there is a discussion of the increasing ties b...

Tests of Quantum Chromodynamics in Exclusive E+e-and Ye Processes*

One of the most, important area.s of investigation in quantum chromodynamics are few-hod3, exclusive reactions initiated by electromagnetic initial states. such as e'e-i HH t+tt-> + ?H. and the two-photon processes 77-+ Hfi shown in Fig. 1. The simplicity. of the photon's couplings to the quark currents and the a.bsence of initial state hadronic interactions allows one to st,ud>. the process of...

On the modular curves YE(7)

Let E denote an elliptic curve over Q and Y E (7) the modular curve classifying the elliptic curves E over Q such that the representations of Gal(Q/Q) in the 7-torsion points of E and of E are symplectically isomorphic. In case E is given by a Weierstraß equation such that the c 4 invariant is a square, we exhibit here nontrivial points of Y E (7)(Q). From this we deduce an infinite family of c...
