Problem 4: Geometric Representation Theory of Graphs on Complex Surfaces Explore the theory of representing graphs geometrically on complex surfaces, such as the complex projective plane CP² 2. Complex Surfaces and Graph Homology: • Given a graph G embedded on CP2, calculate its homology groups over the complex field C and relate this to the graph's properties, such as connectivity and genus. 3. Graph Automorphisms and Complex Structures: Show that for any graph automorphism of a graph embedded on CP², there exists a corresponding complex conjugation symmetry in the embedding. Prove that this automorphism group is isomorphic to the fundamental group of the graph when embedded in CP². 4. Lifting to Higher Dimensions: • Consider lifting the graph embedding from CP² to CP3. Describe the conditions under which such a lift is possible and calculate the resulting changes in homology and fundamental group structure.
