Normal Forms of Real Symmetric Systems with Multiplicity

Dedicated to Jaap Korevaar on the occasion of his 70th birthday. Abstract. A normal form is given for real symmetric systems of linear partial diierential equations, at points where the principal symbol has a two-dimensional kernel under assumptions which apply to the generic case.

Normal Forms for Skew-symmetric Matrices and Hamiltonian Systems with First Integrals Linear in Momenta

Using an appropriate notion of equivalence, those classical Hamiltonian systems which admit a first integral of motion polynomial of degree one in momentum are classified. The classification is effected by means of finding a normal form for a skew-symmetric matrix under the action of orthogonal symmetry.

Normal Forms of Real Hypersurfaces with Nondegenerate Levi Form

We present a proof of the existence and uniqueness theorem of a normalizing biholomorphic mapping to Chern-Moser normal form. The explicit form of the equation of a chain on a real hyperquadric is obtained. There exists a family of normal forms of real hypersurfaces including Chern-Moser normal form. 0. Introduction Let M be an analytic real hypersurface with nondegenerate Levi form in a comple...

Normal forms based fuzzy systems

Normal forms have been introduced as approximating relations for fuzzy relations. Moreover, they can be viewed as a formalization of a collection of fuzzy IF-THEN rules. Therefore, investigation of approximating abilities of normal forms together with determination of an appropriate inference engine contributes to building of fuzzy systems.

Multiplicity of Positive Solutions of laplacian systems with sign-changing weight functions

In this paper, we study the multiplicity of positive solutions for the Laplacian systems with sign-changing weight functions. Using the decomposition of the Nehari manifold, we prove that an elliptic system has at least two positive solutions.
