Corrigendum to “Mild solutions of semilinear elliptic equations in Hilbert spaces” [J. Differential Equations 262 (2017) 3343–3389] (S0022039616304405) (10.1016/j.jde.2016.11.031))

The authors regret to point out some errors in the sign in some equations. Precisely, the signs have to be corrected as follows. • At p. 3346, the correct expression of the formal operator [Formula presented] is [Formula presented]• At p. 3358, the correct expression of (3.5) is [Formula presented]• At p. 3379 and 3380, the correct expressions of (5.4) and (5.9) are, respectively [Formula presented]• At p. 3385, the correct expression of (5.31) is [Formula presented] Since all these objects have only a formal role in the paper, these changes of sign do not affect the proofs. Indeed the proofs only involve the concept of mild solution (3.10), considered with the correct sign. The authors would like to apologise for any inconvenience caused.
