Abstract

Long ago, since 1951, Lyra proposed a modification of Riemannian geometry. Based on the Lyra's modification on Riemannian geometry, Sen and Dunn constructed a field equation which is analogous to Einstein's field equations. Further more, Sen and Dunn gave series type solution to the static vacuum field equations. Retaining only a few terms, we have shown that their solutions correspond to black holes (we call, Lyra black holes). Some interesting properties of the Lyra black holes are studied.
