Ivan Gutman focuses on Combinatorics, Discrete mathematics, Graph, Topological index and Molecular graph. As part of the same scientific family, Ivan Gutman usually focuses on Combinatorics, concentrating on Eigenvalues and eigenvectors and intersecting with Graph theory. His work investigates the relationship between Discrete mathematics and topics such as Degree that intersect with problems in Structure.

The study incorporates disciplines such as Neighbourhood and Topology in addition to Topological index. His Molecular graph research includes themes of Molecule, Chemical graph theory and Hosoya index. His studies in Chemical graph theory integrate themes in fields like Conjugated system and Molecular orbital.

Ivan Gutman spends much of his time researching Combinatorics, Discrete mathematics, Computational chemistry, Graph and Molecule. His research investigates the connection with Combinatorics and areas like Eigenvalues and eigenvectors which intersect with concerns in Laplace operator. His study in Line graph, Graph power, Graph energy, Distance-regular graph and Connectivity are all subfields of Discrete mathematics.

Ivan Gutman combines subjects such as Conjugated system, Electron energy and Hydrocarbon with his study of Computational chemistry. Conjugated system and Ring are frequently intertwined in his study. His studies deal with areas such as Electron and Stereochemistry as well as Molecule.

His primary areas of study are Combinatorics, Discrete mathematics, Graph, Topological index and Degree. Ivan Gutman works mostly in the field of Combinatorics, limiting it down to concerns involving Eigenvalues and eigenvectors and, occasionally, Matrix. He usually deals with Graph and limits it to topics linked to Laplace operator and Invariant.

His research in Topological index intersects with topics in Structure, Topology and Molecular graph. His Vertex study incorporates themes from Neighbourhood and Bound graph. Ivan Gutman interconnects Strongly regular graph and Energy in the investigation of issues within Graph energy.
