<p>Should I take Partial Differential Equations I or Differential Geometry? </p>
<p>I am a double major in physics and math.</p>
<p>Normally, I would say PDE for the Math/Physics combo but we need to know your emphasis area before being able to help you with an answer.</p>
<p>I’m kind of surprised you don’t have an advisor at school to help you with this question.</p>
<p>What about Partial Differential Geometry</p>
<p>GLOBALTRAVELER - Well, I have no particular emphasis in any specific area in mathematics; I am still an undergraduate. But if I did, it will be topology or astrophysics, with that said should I consider Differential Geometry?</p>
<p>Also, what I am not interested is applied aspects of math, I like pure math.</p>
<p>You may want to ask your math and physics faculty advisers, but partial differential equations is probably helpful for physics, while differential geometry is more of a pure math topic.</p>
<p>I would think Differential Geometry may play a role in Astrophysics but then again, I know there are schools that offer courses like “Theory of Partial Differential Equations”, so the PDE course does not have to be applied.</p>
<p>You may not want to hear this but the decision is really a toss up.</p>
<p>Thanks guys for your replies. I am leaning towards Differential Geometry so far.</p>
<p>You need differential geometry for general relativity.</p>
