Title: On general $(α, β)$-metrics of weak Landsberg type,
Abstract: In this paper, we study general $(\alpha,\beta)$-metrics which $\alpha$ is a
Riemannian metric and $\beta$ is an one-form. We have proven that every weak
Landsberg general $(\alpha,\beta)$-metric is a Berwald metric, where $\beta$ is
a closed and conformal one-form. This show that there exist no generalized
unicorn metric in this class of general $(\alpha,\beta)$-metric. Further, We
show that $F$ is a Landsberg general $(\alpha,\beta)$-metric if and only if it
is weak Landsberg general $(\alpha,\beta)$-metric, where $\beta$ is a closed
and conformal one-form.
