Two-dimensional (2-D) polynomial phase signals occur in different areas of image processing. When the degree of the polynomial is two they are called chirp signals. In this paper, we consider the ...
In this paper we consider cubic polynomial systems of the form: ẋ = y + P(x, y), ẏ = -x + Q(x, y), where P and Q are polynomials of degree 3 without linear part ...
