Title
A degree sequence variant of balanced bipartition problem of graphs.
Abstract
Let pi = (d(1), d(2), . . . , d(n)) be a graphic sequence of nonnegative integers. A balanced bipartition of pi is a bipartition pi(1) and pi(2) such that - 1 <= vertical bar pi(1)vertical bar - vertical bar pi(2)vertical bar <= 1, where vertical bar pi(i)vertical bar (i = 1, 2) is denoted to the number of elements of pi(i). In this paper, we determine that every k-regular graphic sequence admits a maximum balanced bipartition pi(1), pi(2) which values about left perpendicular n/2 right perpendicular . min{inverted right perpendicular n/2 inverted left perpendicular, k}. We also show that every graphic sequence pi = (d(1), d(2), . . . , d (inverted right perpendicular n/2 inverted left perpendicular), d (inverted right perpendicular n/2 inverted left perpendicular +) (1) , . . ., d(n)) with d (inverted right perpendicular n/2 inverted left perpendicular) >= left perpendicular n/2 right perpendicular has a balanced bipartition no less than Sigma(n)(i) (=) (inverted right perpendicular n/2 inverted left perpendicular +) (1) d(i) if d (inverted right perpendicular n/2 inverted left perpendicular +) (1) <= inverted right perpendicular n/2 inverted left perpendicular - 1 and d(1) - d (inverted right perpendicular n/2 inverted left perpendicular) <= 2.
