 thermoplyae Yes, unless you mean the conjugate transpose, in which case you... transpose babonk 4*(4^x - 1)/3 + 1 happens to be all the numbers that get you to the 2^x's after (3x+1)/2 MrKeuner thermoplyae: so if a non imaginary matrix A is hermitian if it is equal to A^T TRWBW MrKeuner: you might mean conjugate transpose if you are talking about hermition matrix. that's just its transpose for a real matrix thermoplyae Right, if it's self-adjoint MrKeuner being self-adjoint == being symmetric? thermoplyae For real-valued matrices, yes TRWBW MrKeuner: you need the conjugation with complex numbers so that dot product ends up be a real number, using conjugate transpose follows from that. Anil hi maks __mikem Who just got banned? Anil well, a troll. ihope Here's an interesting symbol: FatalError aleph? maks Hi Anil :) medfly N for someone with my eyesight.. ;) FatalError ;P ihope That's the symbol for the natural numbers. Dreadshoot what symbol? FatalError not usually action __mikem is reading the book, "An Imaginary Tale, the story of the square root of -1" __mikem is reading the book, "An Imaginary Tale, the story of the square root of -1" ihope Actually, it's a DOUBLE-STRUCK CAPITAL N. FatalError usually it's the "blackboard style" N ihope __mikem: I have that! FatalError \mathbb{N} ;) ihope At least, I think I do. FatalError but here the "N" you printed showed as an Aleph(a hebrew letter) ihope You sure it's an aleph? FatalError it's what it showed up as here ihope What about this: thermoplyae Here's something for you guys to chew on: http://www.mathbin.net/9662 FatalError ihope, I wouldn't count on our IRC clients all using the same character set anyway thermoplyae Someone on here showed yesterday that it tended to zero, but I'm not convinced (mostly because I didn't understand) ihope Yes, I know. Dreadshoot nvm Manyfold thermoplyae: sum_i n choose i =2 ^n Kampen that showed up as aleph for me too ihopethe first one showed up as the blackboard bold for naturals thermoplyae Yeah, I agree that it's bounded from above by 1
