Do they tend to be liberal, conservative, or .. ??? The American atheist guy, David silverman, claims to be a conservative.Read more

I am not sure who exactly to identify with. Each party has their own flaws and I just can’t decide where exactly I am. If you could give a diagnosis, it would be greatly appreciated. Ok here goes: I believe in freedom of speech, pro-second amendment (except I also believe that there should be psychRead more

i am pro-choice and support funding on planned parenthood. i believe marijuana should be legalized in the federal level with a legal age of 18 i think the drinking age in america should be lowered to 18 since i think 21 is too high i believe in lgbtq rights and genderless bathrooms, i support equalRead more

I’m working on the adjacency matrix of some graphs and need some facts about Hermitian matrices which have exactly two distinct eigenvalues. Can anybody help me introduce source about spectrum of Hermitian matrices or more generally about these matrices? Bests.Read more

Spectrum interned promise 100mbps on their internet speeds but i never get that. I have taken their own speed test and top out on a good day of about 43mbps but I’m averaging about 23mbps. When i ask them they can’t give me a wander and sent someone out who says there is nothing wrong?Read more

Let $ \cal A$ denote the mod 2 Steenrod algebra. Can the $ \mathcal{A}(2)$ -module structure on $ \mathcal{A}(2)//\mathcal{A}(1)$ be enriched to an $ \cal A$ -module structure? If so, is there a finite spectrum $ X$ such that $ H^*(X) = \mathcal{A}(2)//\mathcal{A}(1)$ ?Read more

consider the equation dx/dt=A(t)x where A(t+T)=A(t),its fundamental matrix is P(t)e^tQ,where P(t+T)=P(t),eigenvalue of Q called exponential index. L is defined as -dx/dt+A(t)x,is a linear operator from C1 to C,I proved that spectrum of L are exponential index. Can there be deeper relationship between DS and spectrum following this way?Read more

Is the support of the Brown measure of an operator always contained in the spectrum of the operator as a set? When is it equal to the spectrum?Read more

If $ A$ is a Banach algebra and $ a \in A$ is an idempotent, it is well known that $ \sigma(a) = \{0; 1\}$ . Is the converse true ?, ie if $ \sigma (a) = \{0; 1\}$ does it mean that $ a$ is an idempotent ?Read more

With W(n) being the discrete-time white noise signal with variance equals to 5 (either uniformly distributed and symmetric, or Gaussian), simulate long samples of the signal y(n) = w(n) + 0.5w(n-1)-0.3(n-2) Derive and plot the power spectrum density of Y via both the periodogram formula myP = WhiteNoiseProcess[Sqrt[5]]; data = RandomFunction[myP, {0, 40}]; newdata =Read more
