چکیده

Let F=(f,g):R2?R2 be a polynomial map such that det?(DF(x,y)) is nowhere zero and F(0,0)=(0,0). In this work we give new sufficient condition for the injectivity of F. We also state conjecture when det?(DF(x,y))= constant ?0 F(0,0)=(0,0) equivalent to Jacobian conjecture.

A new qualitative proof of a result on the real Jacobian conjecture.

Let F= (f, g) : R2 → R2 be a polynomial map such that det DF(x) is different from zero for all x ∈ R2. We assume that the degrees of f and g are equal. We denote by f and G the homogeneous part of higher degree of f and g, respectively. In this note we provide a proof relied on qualitative theory of differential equations of the following result: If f and g do not have real linear factors in co...

On the Jacobian Conjecture

The Jacobian Conjecture can be generalized and is established : Let S be a polynomial ring over a field of characteristic zero in finitely may variables. Let T be an unramified, finitely generated extension of S with T = k . Then T = S. Let k be an algebraically closed field, let k be an affine space of dimension n over k and let f : k −→ k be a morphism of algebraic varieties. Then f is given ...

A New Sufficient Condition of Hamiltonian Path

A Hamiltonian path is a spanning path in a graph i.e. a path through every vertex. In this paper we present an interesting sufficient condition for a graph to possess a Hamiltonian path. In particular we prove that the degree sum of all pairwise nonadjacent vertex-triples is greater than 1/2(3n 5) implies that the graph has a Hamiltonian path, where n is the number of vertices of that graph. Al...

A new sufficient condition for hamiltonian graphs

The study of Hamiltonian graphs began with Dirac’s classic result in 1952. This was followed by that of Ore in 1960. In 1984 Fan generalized both these results with the following result: If G is a 2-connected graph of order n and max{d(u), d(v)}≥n/2 for each pair of vertices u and v with distance d(u, v)=2, then G is Hamiltonian. In 1991 Faudree–Gould–Jacobson–Lesnick proved that if G is a 2-co...
