Abstract
The open inflation model recently proposed by Hawking and Turok is investigated in scalar-tensor gravity context. If the dilaton-like field has no potential, the instanton of our model is singular but has a finite action. The Gibbons-Hawking surface term vanishes and hence, can not be used to make nonzero. To obtain a successful open inflation one should introduce other matter fields or a potential for the dilaton-like fields.
