How does the following expression $$ds^2= \frac {dx^2+dy^2} {y^2}$$ specify a riemannian metric on $h$
I don't understand what the. Given a riemannian metric on r2, ds R2 is an isometry if and only if ds is invariant under f Assume r2 has the standard euclidean metric, and let f
We have to calculate the second derivative of the area of the circle respected to time and express your answer using the ricci tensor The tensor field ds2 = dx2 + dy2 d s 2 = d x 2 + d y 2 tells you that it assigns to each point the tensor ⋅, ⋅ , , i.e Ds2 d s 2 is a function that sends each point p ∈r2 p ∈ r 2 to ⋅, ⋅ ,. The problem i've tried to solve without success is the following
Find the coordinate transformation from cartesian (where ds2 = dx¯2 + dy¯2 d s 2 = d x ¯ 2 + d y ¯ 2) that brings the following.
(b) find the metric in spherical polar coordinates ⇢ sin )2 + (d⇢ sin + ⇢ cos )2 n2 ) + ⇢2d 2(sin2 + cos2 ) = d⇢2 adding dz2 gives the desired result (d) start with ds2 = d⇢2 + ⇢2d 2 + dz2 Now ⇢2 = r2 sin2 and the product rule applied.
Let (t, x, y, z) (t, x, y, z) be the standard coordinates on r4 r 4 and consider the minkowski metric Ds2 = −dt2 + dx2 + dy2 + dz2 D s 2 = d t 2 + d x 2 + d y 2 + d z 2 I am trying to compute the.
