theorem Th29: :: GLIB_012:29

for G3, G4 being _Graph
for V1, V2 being set
for G1 being addLoops of G3,V1
for G2 being addLoops of G4,V2
for F0 being PGraphMapping of G3,G4 st V1 c= the_Vertices_of G3 & V2 c= the_Vertices_of G4 & (F0 _V) | V1 is one-to-one & dom ((F0 _V) | V1) = V1 & rng ((F0 _V) | V1) = V2 holds
ex F being PGraphMapping of G1,G2 st
( F _V = F0 _V & (F _E) | (dom (F0 _E)) = F0 _E & ( not F0 is empty implies not F is empty ) & ( F0 is total implies F is total ) & ( F0 is onto implies F is onto ) & ( F0 is one-to-one implies F is one-to-one ) & ( F0 is directed implies F is directed ) & ( F0 is weak_SG-embedding implies F is weak_SG-embedding ) & ( F0 is isomorphism implies F is isomorphism ) & ( F0 is Disomorphism implies F is Disomorphism ) )
