## Abstract A 1βfactorization is constructed for the line graph of the complete graph __K~n~__ when __n__ is congruent to 0 or 1 modulo 4.
The paper describes several algorithms related to a problem of computing the local dimension of a semialgebraic set. Let a semialgebraic set V be defined by a system of k inequalities of the form f β₯ 0 with f β R[X 1 , . . . , Xn], deg(f ) < d, and x β V . An algorithm is constructed for computing t
classes among the edges of a graph For two edges e = (x, y) and e ' = (x', y') of a connected graph G = (V, E) let e Oe' iff d(x. x') + ;(y, y') # d(x, y') + d(x', y). Here d(x, y) denotes the length of a shortest path in G joining vertices x and y. An algorithm is presented that computes the equiva
