    Undergrad Klein-Gordon: Schwarzschild Metric, Physically Acceptable?

    I meant to include in the previous post the presence of gravity or the absence of a field.

    Undergrad Klein-Gordon: Schwarzschild Metric, Physically Acceptable?

    When you say absence of non-gravitational interactions within the field you mean to say that solving this for the Schwarzschild is effective in explaining wave-like phenomena in the presence of gravity exclusively?

    Chances of Getting Into Grad School with a B-

    My physics GPA is a 3.273 apparently. I also have research experience and an internship and an applied BS degree in mathematics (3.6 GPA) which was noted on my graduate applications.

    Undergrad Klein-Gordon: Schwarzschild Metric, Physically Acceptable?

    If you use the Schwarzschild metric in the Klein-Gordon equation (see attached) and derive the equation for the particle as a function of its position in time and space, do you get physically realizable solutions? This is my question.

    Chances of Getting Into Grad School with a B-

    I got a B- in two physics courses. I'm a senior and it is my last semester. What do you think my chances are of getting in? One of these was a problem solving course from a few years ago and I got a B- in quantum because I didn't study angular momentum operators (The last thing we did in class)...

    Undergrad Klein-Gordon: Schwarzschild Metric, Physically Acceptable?

    Does this give solutions which are physically acceptable?

    Undergrad Infinite series calculation of a potential

    I'm trying to get from the formula in the top to the formula in the bottom (See image: Series). My approach was to complexify the sine term and then use the fact that (see image: Series 1) for the infinite sum of 1/ne^-n. Then use the identity (see image: Series 2). Any other ideas?

    Undergrad Convert 2x2 Matrix to 1x1 Tensor

    Solved. Thanks! By the way there is a nice problem about this in A First Course In General Relativity by Schutz (Chapter 3, problem 24)

    Undergrad Convert 2x2 Matrix to 1x1 Tensor

    I guess not. I'll look it up. Thank you.

    Undergrad Convert 2x2 Matrix to 1x1 Tensor

    I take this to mean I multiply this matrix by a scalar given by the metric tensor g?

    Undergrad Convert 2x2 Matrix to 1x1 Tensor

    The first thing you stated is correct. Say I have a tensor Mab (superscripts) and I apply this metric tensor to this matrix to lower one of its indices - how would I multiply this result out?

    Undergrad Convert 2x2 Matrix to 1x1 Tensor

    Sorry - these should be proper super/subscripts.

    Undergrad Convert 2x2 Matrix to 1x1 Tensor

    If I have a matrix representing a 2nd order tensor (2 2) and I want to convert this matrix from M$$\textsuperscript{ab}$$ to $$M\textsubscript{b}\textsuperscript{a}$$ what do I do? I'm given the matrix elements for the 2x2 tensor. When applying the metric tensor to this matrix I understand...
