An unbiased random generator for binary trees is developed for a CREW-PRAM. The generator is capable of generating a binary tree on \(n\) nodes in time \(O(\log n)\), space \(O(n)\), with \(O(n)\) processors; it is also capable of generating various related combinatorial objects.

Let \(X\) be a universal cover of a finite connected graph, and \(\Gamma\) a group acting discretely and cocompactly on \(X\), i.e., a uniform lattice on \(X\). We announce a proof of the conjecture of H. Bass and R. Kulkarni (J. Amer. Math. Soc. No. 4 (1990), 843-902) that the commensurability grou
Denote by e\*(L) and ~,(L) respectively the upper length and lower length of a finite lattice L. The lattice L is said to be uniform if for each integer k with e,(L) < k < ยข\*(L) there exists in L a maximal chain of length k. It is shown that the closed-set lattice of a finite graph G is uniform if
