Abstract
The paper is devoted to the solvability of semilinear operator equations in Banach spaces, via continuation methods. Instead of degree methods, the author makes use of the notion of essential map. A no-degree version of an important continuation principle due to A. Capietto, J. L. Mawhin and F. Zanolin [J. Differential Equations 88 (1990), no. 2, 347–395; MR1081252] is also given.
