Sigbjørn Hervik

Sigbjørn Hervik is a Professor in the Department of Mathematics and Physics at the University of Stavanger, Faculty of Science and Technology. His research lies at the intersection of differential geometry, general relativity, and mathematical physics.

His research interests include:

• Differential Geometry and Pseudo-Riemannian Metrics
• Universal Spacetimes and Black Holes
• Classification of Gravitational Fields via Curvature Invariants
• Exact Solutions in General Relativity and Higher Dimensions
• Anisotropic and Inhomogeneous Cosmological Models
• Applications of Lie Theory and Symmetry in Physics

His recent publications reveal a consistent focus on universal spacetimes, CSI (Constant Scalar Invariant) metrics, Kundt geometries, and the algebraic classification of spacetimes using scalar invariants. He frequently explores higher-dimensional generalizations and connections with supergravity and modified gravity theories. His work often involves collaboration with leading researchers in mathematical relativity.

Scientific contributions and collaborations include:

• Co-editor of conference proceedings on Geometry, Lie Theory and Applications (Abel Symposium 2019)
• Key contributions to the classification of Weyl tensors in higher dimensions
• Studies on tilted Bianchi cosmologies with diffusion and anisotropic inflation
• Work on LISA mission prospects for fundamental physics

He has advised or collaborated with numerous researchers and students, though a formal list is not provided. He has also engaged in public outreach, including opinion pieces in the Stavanger Aftenblad. No formal scientific awards are listed in the available data.
