theorem Th145: :: GLIB_010:145

for G3, G4 being _Graph
for V1, V2 being set
for G1 being addVertices of G3,V1
for G2 being addVertices of G4,V2
for F0 being PGraphMapping of G3,G4
for f being one-to-one Function st dom f = V1 \ (the_Vertices_of G3) & rng f = V2 \ (the_Vertices_of G4) holds
ex F being PGraphMapping of G1,G2 st
( F = [((F0 _V) +* f),(F0 _E)] & ( F0 is weak_SG-embedding implies F is weak_SG-embedding ) & ( F0 is strong_SG-embedding implies F is strong_SG-embedding ) & ( F0 is isomorphism implies F is isomorphism ) & ( F0 is Disomorphism implies F is Disomorphism ) )
