The [Theta]-operator and the low hierarchy
(1992-07)
Research report
Open AccessLong and Sheu in their paper [LS-91] introduced a refinement of the low hierarchy based on the [Theta]-levels of the polynomial time hierarchy which gives a deeper sight of the internal structure of NP. In this paper we ... -

Characterizations of some complexity classes between [theta sub 2 super p] and [delta sub 2 super p]
(1990)
Research report
Open AccessWe give some characterizations of the classes P super NP [0(log super k n)]. First, we show that these classes are equal to classes AC super k-1 (N P). Second, we prove that they are also equivalent to some classes defined ... -
Development of algebraic specifications with constraints
(1989)
Research report
Open AccessA formal framework for the development of algebraic specifications is presented. Ther main issues concerning the approach are the following: we allow to deal with incomplete specifications during the design process. This ... -

Trees whose even-degree vertices induce a path are antimagic
(2019-05-16)
Research report
Open AccessAn antimagic labeling of a connected graph G is a bijection from the set of edges E(G) to {1, 2, . . . , |E(G)|} such that all vertex sums are pairwise distinct, where the vertex sum at vertex v is the sum of the labels ...
