Some functorial properties are studied for the Hörmander classes defined for symplectic bundles. The behaviour of the Chern first form on a Lagrangian submanifold in an almost Hermitian manifold is also studied, and Fomenko's conjecture about the behaviour of a Maslov class on minimal...

Let ⊕ = max(, ), ⊗ = + for . By max-algebra we understand the analogue of linear algebra developed for the pair of operations (⊕, ⊗) extended to matrices and vectors. Max-algebra, which has been studied for more than 40 years, is an attractive way of describing a class of nonlinear...
