R. of IranJournal Article20060927We prove that every R-quadratic metric of scalar flag curvature with a dimension greater than two<br />is of constant flag curvature. Then we show that generalized Douglas-Weyl metrics contain R-quadratic<br />metrics as a special case, but the class of R-quadratic metric is not closed under projective transformationshttp://ijsts.shirazu.ac.ir/article_2303_b1d104fd19fc0b74b7c8c77b82ef8f94.pdf
