本文考虑一个具有耦合函数f（ω）的广义Einstein-scalar-Gauss-Bonnet理论。我们证明，黑洞的解决方案出现作为一个通用的功能，这个理论，因为一个正规的地平线和渐近平坦的解决方案可以很容易地构造下温和的假设f（）。我们证明了现有的无毛定理是容易回避的，然后对大量的耦合函数f（f）给出了大量的具有标量毛的正则黑洞解。
We consider a general Einstein-scalar-Gauss-Bonnet theory with a coupling function f(ϕ). We demonstrate that black-hole solutions appear as a generic feature of this theory since a regular horizon and an asymptotically flat solution may be easily constructed under mild assumptions for f(ϕ). We show that the existing no-hair theorems are easily evaded, and a large number of regular black-hole solutions with scalar hair are then presented for a plethora of coupling functions f(ϕ).
