Computing Fourier transforms and convolutions of Sn-1-invariant signals on Sn in time linear in n
Let Sn denote the symmetric group on {1, . . . , n} and Sn-1 the stabilizer subgroup of n. We derive algorithms for computing Fourier transforms of left and right Sn-1-invariant s...

On Sorting an Intransitive Total Ordered Set Using Semi-Heap
1 The problem of sorting an intransitive total ordered set, a generalization of regular sorting, is considered. This generalized sorting is based on the fact that there exists a s...

Linear Suffix Array Construction by Almost Pure Induced-Sorting
We present a linear time and space suffix array (SA) construction algorithm called the SA-IS algorithm. The SA-IS algorithm is novel because of the LMS-substrings used for the pro...

Optimal Integer Alphabetic Trees in Linear Time
Abstract. We show that optimal alphabetic binary trees can be constructed in O(n) time if the elements of the initial sequence are drawn from a domain that can be sorted in linear ...

Soft lambda-Calculus: A Language for Polynomial Time Computation
Soft linear logic ([Lafont02]) is a subsystem of linear logic characterizing the class PTIME. We introduce Soft lambda-calculus as a calculus typable in the intuitionistic and affi...
