1. The equation is derived by solving the Einstein equations for a general time-invariant, spherically symmetric metric.
2. In both cases, the boundary case of equality is attained by the symmetric metric of the projective plane.
3. The first person to add a non-symmetric metric tensor, while much later Brans and Dicke added a scalar component to gravity.
4. Meanwhile, in the quaternionic case, the symmetric metric on \ mathbb { HP } ^ 2 is not its systolically optimal metric.
5. A "'pseudo-Riemannian manifold "'( M, g ) is a differentiable manifold M equipped with a non-degenerate, smooth, symmetric metric tensor g.
6. It's difficult to find symmetric metric in a sentence. 用symmetric metric造句挺難的
7. where the matrix of coefficients " g " " ij " is the symmetric metric tensor which is called a Ruppeiner metric, defined as a negative Hessian of the entropy function
8. Namely, it was discovered that, contrary to expectation, the symmetric metric on the quaternionic projective plane is " not " its systolically optimal metric, in contrast with the 2-systole in the complex case.
9. In other words, the manifold \ mathbb { HP } ^ 2 admits Riemannian metrics with higher systolic ratio \ mathrm { stsys } _ 4 { } ^ 2 / \ mathrm { vol } _ 8 than for its symmetric metric.
10. If the four spacetime coordinates " x " ?are given in arbitrary units ( i . e . unitless ), then " g " 到 in m 2 is the rank 2 symmetric metric tensor which is also the gravitational potential.
11. In this sense, this is by far the most symmetric metric on the sphere . ( The group of all isometries, known as O ( 3 ), is also 3-dimensional, but unlike SO ( 3 ) is not a connected space .)
12. While the quaternionic projective plane with its symmetric metric has a middle-dimensional stable systolic ratio of 10 / 3, the analogous ratio for the symmetric metric of the complex projective 4-space gives the value 6, while the best available upper bound for such a ratio of an arbitrary metric on both of these spaces is 14.
