Featured researches published by Andrzej Rogowski.

Topological Methods in Nonlinear Analysis | 2003

Periodic solutions of Lagrange equations

Andrzej Nowakowski; Andrzej Rogowski

Nontrivial periodic solutions of Lagrange Equations are investigated. Sublinear and superlinear nonlinearity are included. Convexity assumptions are significiently relaxed. The method used is the duality developed by the authors.
