Graduate (wald) method for calculating curvature
pervect, we have two variables inside the brackets, a and b. ok... but see the curvature tensor: R_{a}_{[b}_{c}_{d]}=0 it is definition equal of the tensor antisymmetric in the brackets? (where it origines ∂[aΓdb]c = ½(∂aΓdbc - ∂bΓdac) ? ) thank very much!- nulliusinverb

Graduate (wald) method for calculating curvature
R_{a}_{b}_{c}^{d}ω_{d}=((-2)\partial_{[a}\Gamma^{d}_{b] }_{c}+2\Gamma^{e}_{[a]}_{c}\Gamma^{d}_{[b]}_{e})ω_{d} good, me question is about of: 1.- as appear the coefficient (-2) und the (2)? 2.- it is assumed that...- nulliusinverb

Graduate Theorem mathematic for relativity
i apologize for the delay, here is the proof: F:ℝ^{n}\rightarrowℝ i have: F(\vec{x})-F(\vec{a})= \sum^{m}_{μ=1}F(t(x^{μ}-a^{μ})+a^{μ},0...,0)^{t=1}_{t=0} then: =\sum^{m}_{μ=1}(x^{μ}-a^{μ})\int^{1}_{0}\frac{\partial F}{\partial u^{μ}}((t(x^{μ}-a^{μ})+a^{μ},0...,0)dt where...- nulliusinverb

Graduate Theorem mathematic for relativity
Fredrick thank you very much, the book is recommended to study this issue, although the theorem is raised from other values is the same. thank! ps: "Modern Differential Geometry for Physicists" autor: Isham- nulliusinverb

Graduate Theorem mathematic for relativity
hello!: my problem is about of a theorem mathematic,as I prove the following theorem? F(x)=F(a) + \sum^{n}_{i=1}(x^{i}-a^{i})H_{i}(x) good first start with the fundamental theorem of calculus: (for proof): F(x) - F(a) = \int^{x}_{a}F'(s)ds sustitution: s=t(x - a) + a...- nulliusinverb

Graduate Problem Landau relativity special
I wanted to delete the entire message but could not, my reason was that I answered my questions, was a simple "binomial series." Anyway I upload issue again. thank you very much.- nulliusinverb
