Items for "zero locations"

Enclosure, separation, and computation of the zeros of exponential trinomials with constant coefficients and real exponential points

After having explained the underlying motivations, we study the location of the zeros of the functions T(z):=Ae^az+Be^bz+Ce^cz of the complex variable z with complex coefficients A, B, C and real a < b < c...
