theorem Th143: :: GLCOLO00:143

for G2 being _Graph
for v, e being object
for w being Vertex of G2
for G1 being addAdjVertex of G2,v,e,w
for t being TColoring of G2
for x, y being object st not e in the_Edges_of G2 & not v in the_Vertices_of G2 holds
[((t _V) +* (v .--> x)),((t _E) +* (e .--> y))] is TColoring of G1
