I miss the guy too. What is he up to if anybody knows?

Not first hand, but they are particularly great at applied maths with some renowned applied mathematicians on their faculty.

Best of luck to both of you! I'll be in your shoes soon enough.

Yeah, Andy's explanation makes sense to me. I was looking through my linear algebra professor's research articles, and a couple of them were communicated by a different person. The articles in question were published in the Proceedings of the AMS -- is that a journal that also requires...

"Communicated by" in a journal article Out of curiosity, why would a journal article be communicated by someone other than the author (or even authors, in some cases that I've seen)?

Jimmy, can you post the descriptions for both classes? I think you would get a more informed opinion this way, for we have no idea of knowing what's taught in both classes.

Trust me, Irwin is a very decent book -- the problems are appropriately challenging and vary in difficulty. It was not required for my class, but it made me ace the final exam for its excellent treatment of power.

Some real analysis (rudin) and linear algebra?

Nice. I like your result -- your notation in the original post is foreign to me though, so I have to dig into that to check your proof -- although I'm sure its fine. :) I also made a little bit of research, and another interesting result dictates loosely that f is uniformly differentiable iff...

This thread is reasonably recent, so I thought I might reiterate your question. I was looking for conditions for which uniform differentiability holds and I found your thread as a Google search result. Have you found what you're looking for?

Well, I'm taking Analysis now, and that's exactly how you show convergence implies Cauchy--that is, without appealing to (1).

I recall having had something similar in Calculus II. Have you tried Ratio test? It's probably more approachable that way.

Ross' Elementary Analysis--that's the text I'm using now for the class. One thing that bears mentioning is that geometric arguments don't appear quite often in Ross (and never in Rudin), so you HAVE to supply those for your own. Since you'll be working on the real line if you use Ross, geometric...

Sara, I'm not an expert on this, as I'm taking the class right now. It works for p = 2/3; that is, you would leave out the 1 and constrain the 0 inside the interval, but it is not an ideal candidate for a contradiction argument. From the outline above, what you're trying to do is simply argue...
