Pseudorandomness for network algorithms
We define pseudorandom generators for Yao's twoparty communication complexity model and exhibit a simple construction, based on expanders, for it. We then use a recursive com...

Calculating the Number of Tunnels
This report1 considers 2-regions of grid cubes and proposes an algorithm for calculating the number of tunnels of such a region. The graph-theoretical algorithm proceeds layer by l...

Herbrand Theorems and Skolemization for Prenex Fuzzy Logics
Approximate Herbrand theorems are established for first-order fuzzy logics based on continuous t-norms, and used to provide proof-theoretic proofs of Skolemization for their Prenex...

Growth of components in random graphs
The creation and growth of components of a given complexity in a random graph process are studied. In particular, the expected number and total size of all such components is found...

Coincidences Are not Accidental: a Theorem
In this paper, we formalize and prove the statement that coincidences cannot be accidental, a statement that underlies many useful heuristics in mathematics and physics. Our proof...
