چکیده

Let $F$ be a non-archimedean local field of residual characteristic $p$. $\mathbb{G}$ reductive group defined over which splits tamely ramified extension and set $G=\mathbb{G}(F)$. We assume that $p$ does not divide the order Weyl $\mathbb{G}$. Given closed connected $F$-subgroup $\mathbb{H}$ contains derived subgroup $\mathbb{G}$, we study restriction to $H$ an irreducible supercuspidal representation $\pi=\pi_G(\Psi)$ $G$, where $\Psi$ is $G$-datum as per J.K. Yu Construction. provide full description $\pi|_H$ into components, with multiplicity, via data constructs $H$-data from $\Psi$. Analogously, define Kim-Yu types representations $G$ are supercuspidal.

Restricting SBH Ambiguity via Restriction Enzymes

Sequencing by hybridization (SBH) is a proposed approach to DNA sequencing. The SBH-spectrum of the target sequence is a list of all k-mers occurring at least once in the sequence. Sequencing is successful if the SBH-spectrum is a result of only that sequence and ambiguous otherwise. Unfortunately, the expected number of sequences consistent with a given spectrum increases exponentially with th...

Construction of Tame Supercuspidal Representations

The notion of depth is defined by Moy-Prasad [MP2]. The notion of a generic character will be defined in §9. When G = GLn or G is the multiplicative group of a central division algebra of dimension n with (n, p) = 1, our generic characters are just the generic characters in [My] (where the definition is due to Kutzko). Moreover, in these cases, our construction literally specializes to Howe’s c...

Supercuspidal Representations: an Exhaustion Theorem

Let k be a p-adic field of characteristic zero and residue characteristic p. Let G be the group of k-points of a connected reductive group G defined over k. In [38], Yu gives a fairly general construction of supercuspidal representations of G in a certain tame situation. In this paper, subject to some hypotheses on G and k, we prove that all supercuspidal representations arise through his const...

Types for supercuspidal representations of GL(N)

We recall here the basic definitions needed to construct simple types, with no proofs given of the many claims that we make. For a much more detailed account, see [1] and the many other sources cited therein. Note that most of the statements made here could be proven without much difficulty for the reader who has the time and inclination. Any statements requiring a much more elaborate proof are...

Refined Anisotropic K-types and Supercuspidal Representations

Let G be any connected reductive group defined over a nonarchimedean local field F of residual characteristic p. Under some tameness assumptions on G, we construct families of positive-depth supercuspidal representations of G = G(F ). In particular, we classify (§2.7) the representations of G that contain any anisotropic unrefined minimal K-type (in the sense of MoyPrasad [28]) that satisfies a...
