Ján Brajerčík

Ján Brajerčík is an Associate Professor at the Department of Physics, Mathematics and Techniques, University of Presov, Slovakia, and a member of the Lepage Research Institute. His research focuses on advanced mathematical structures in theoretical physics.

• Position: Associate Professor
• Affiliation: University of Presov, Lepage Research Institute

His research interests lie in the calculus of variations on fibred manifolds, geometry of principal bundles, and differential invariants, with applications to mechanics and general relativity. Recent work explores the topology of Schwarzschild spacetimes and canonical decompositions of SO(3), alongside educational studies on cognitive function stimulation in mathematics teaching.

Collaborations include institutions such as the Union of Czech Mathematicians and Physicists, Eötvös Loránd University, and the International Visegrad Fund. Trends in his publications reflect a blend of pure geometric analysis and interdisciplinary educational research.
