Conrad pulled down the mask. The man gazed at Wilkes, whose expression went from exasperation to shock.
For the Poincaré half-space model in dimension 2, the metric evaluates on the coordinate tangent vectors \(\frac{\partial}{\partial x}, \frac{\partial}{\partial y} \in T_pM\) as \[g_p\!\left(\frac{\partial}{\partial x^i}\bigg|_p,\;\frac{\partial}{\partial x^j}\bigg|_p\right) = \frac{1}{y^2}\,\delta_{ij},\] i.e. the coordinate tangent vectors are orthogonal and each has length \(\frac{1}{y}\) — shrinking to zero as \(p\) approaches the boundary \(y\to 0\), which is what makes the space “infinitely large” near the boundary.。关于这个话题，WPS官方版本下载提供了深入分析

“I just said: ‘This isn’t going to work, guys, your mom is not going to be part of this discussion, so we’re going to have to shut her down, or you’re not going to be considered for this role,’” O’Leary recalled.
