Various new nonembeddability results (mainly into L1) are proved via Fourier analysis. In particular, it is shown that the Edit Distance on {0, 1}d has L1 distortion (log d) 1 2 â...
We establish a new connection between the two most common traditions in the theory of real computation, the Blum-Shub-Smale model and the Computable Analysis approach. We then use...
This paper proves  ¡ £ ¥ lower bounds on the time to perform a single instance of an operation in any implementation of a large class of data structures shared by £ processe...
In joint work with ´Eva Tardos in 1995, we asked whether it was possible to obtain a polynomial-time, polylogarithmic approximation algorithm for the disjoint paths problem in th...
We consider online problems where purchases have time durations which expire regardless of whether the purchase is used or not. The Parking Permit Problem is the natural analog of...
