I suggest to burninate discrete-series. It has 7 occurrences at the time I'm writing. 4 of them are concerned with the meaning of discrete series in the context of the classification of unitary representations of semisimple Lie groups or analogues (the "space" of irreducible unitary representa...
Let $(J,\pi)$ be a cuspidal type in $SL(2,F)$, $F$ is a non-Arch. local field and let $I$ be the Iwahori subgroup of $SL(2,F)$. Is there any possibility that $J\subset I$ or even a subgroup?
I am working on the chamber homology for $SL(2,F)$, and stuck at some basic stuff on D.S. reps of $SL(2,F)$. Let $ I=\left( \begin{array}{cc} \mathcal{O}_{F} & \mathcal{O}_{F} \\ \varpi_{\mathbb{F}}\mathcal{O}_{F} & \mathcal{O}_{F}\\ \end{array} \right)\cap ...
I am looking for research that has been done in Discrete wavelets. Let me be specific as Google doesn't give me what I want when I say "discrete wavelets". I don't want countable basis for $ L^2(\mathbb{R}) $, Daubechies book, "Ten Lectures on Wavelets", already has this. I am looking for resear...
This function has been explored a bit at MSE (in June 2016): \begin{eqnarray} f(n) &=& (n-1)^2 \; \textrm{if} \; (n \bmod 4) = 1\\ f(n) &=& \lfloor n/4 \rfloor \; \textrm{otherwise} \end{eqnarray} with $f^k(n) = f(f( \cdots (n) \cdots ) )$ the result of applying $f(\;)$ $k$ times to $n$. The anal...
Goal. I would like to calculate the product of the formal dimension of a discrete series representation of $GL(2,\mathbb{Q}_p)$ with trivial central character (so, an irreducible unitary representation of $PGL(2,\mathbb{Q}_p)$ that is a subrepresentation of $L^2(PGL(2,\mathbb{Q}_p))$) and the c...
QUESTION Let $G$ be a simple Lie group with equal rank; namely, the rank of $G$ equals the rank of its maximal compact subgroup. Suppose that $G'$ is a reductive subgroup of $G$ with equal rank. If $\pi$ is a discrete series representation of $G$, is its restriction $\pi|_{G'}$ a discrete series...
