Re: Field: Logic

Personally I find logic to be a very interesting field, and Notre Dame is certainly a good place to study it, so you'll get no warning from me. Do you have any particular interests within logic? Like computability, or model theory? Or even more specific, like reverse math, or computable model theor...

Field: Logic

Sorry for having two active topics going at once, I don't mean to spam up the place. I have been toying with the idea of studying logic in grad school. I will be a senior undergrad next year, but is there anyone in the field here that wants to give some warning/ reinforcement to my interest? One of ...

Re: What exactly do you do for math research projects?

For the most part I agree with everyone else on this. It also depends on your mentor and if it is a group or individual research project. each one has it's benefits. With groups, everyone has to be up to speed and on the same page essentially, so it can slow it down but makes more "predictable&...

Re: lights out

If you are interested in some more non-orthodox lights out puzzles (and solutions), email Les Shader, an emeritus prof. here at the University of Wyoming or msg me. :D He's been working on these things way before Tiger even made their game and his specialty is in Puzzles and Linear Alg.

Re: Serre's relations for specific family of Cartan matrices

I also forgot to mention: free candy in a white unmarked van for whoever gives me a good answer!
Seriously though it's for a much deeper research question that could have awesome results.

You know, it is absolutely cruel that you posted this... I spent like 3 hours of research time toying with the problem! Nice work by the way. Very clever set of solutions so far.

Re: Thank you for #435

Unfortunately, this happens to be my only soap box issue, so I have to throw this out there. I don't think it is as simple as women have a different "preference". For me, it starts at home. Growing up, I was taught that men are naturally (ie. by NATURE not nurture) better at problem solvin...

Serre's relations for specific family of Cartan matrices

So I'm hoping someone has worked with (Chevalley)-Serre's relations before. I was wondering if there is a nice known way to generate the multiplication tables for the family of Cartan Matrices [[2, -n][-1, 2]] (Ignoring the f_i 's) where n geq 4. ie. the table consisting of the Lie products of: [{h_...

Re: Wreath Products (Run away!)

So if what I stated WAS a wreath product, then what is a generic semi-direct product? I mean, I read the wiki definition and all, but if you gave me the two subgroups to make the group via semi-direct product, I would be at a loss. as for the decomp, let's see if i can get the imath to work... here'...

Re: Wreath Products (Run away!)

It is my understanding that semi-direct products are essentially n-tuples of the first set cross the second set. Although this is the first day I encountered them both the semi-direct products and wreath products), I think my real flaw in understanding is the decomposition of the group of permutatio...

Re: Asking for a recommendation (REU)

If you need them to send in information via the internet for the REU then yes, email them regardless. Also it'll be a constant reminder in their inbox so they don't forget. I always ask for mine and then ask them in person if they got my email to confirm that they will. I got great recs every time. ...
