Cell types can be classified according to shared patterns of transcription. Non-genetic variability among individual cells the same type has been ascribed stochastic transcriptional bursting and transient cell states. Using high-coverage single-cell RNA profiling, we asked whether long-term, heritable differences in gene expression impart diversity within type. Studying clonal human lymphocytes mouse brain cells, uncovered a vast different clones vivo. We combined chromatin accessibility...

Smooth irreducible representations of tori over local fields have been parameterized by Langlands, using class field theory and Galois cohomology.This paper extends this parameterization to some central extensions such tori, which arise naturally in the setting nonlinear covers reductive groups.

In this joint introduction to an Asterisque volume, we give a short discussion of the historical developments in study nonlinear covering groups, touching on their structure theory, representation theory and automorphic forms. This serves as motivation sets scene for papers volume. Our is necessarily subjective will undoubtedly leave out contributions many authors, whom apologize earnest.

Given a reductive group $\mathbf {G}$ over base scheme $S$, Brylinski and Deligne studied the central extensions of by {K}_2$, viewing both as sheaves groups on big Zariski site $S$. Their work classified these three invariants, for $S$ spectrum field. We expand upon their to study “integral models” such extensions, obtaining similar results sufficiently nice ring, e.g., DVR with finite residue field or containing Milder are obtained Dedekind domain, often conditional Gersten’s conjecture.

Langlands has described the irreducible admissible representations of $T$, when $T$ is group points an algebraic torus over a local field. Also, automorphic $T_{\Bbb{A}}$ adelic global field $F$. We describe (in setting) and $\epsilon$-genuine for ``covers'' tori, also known as ``metaplectic tori,'' which arise from framework Brylinski Deligne. In particular, our results include description spherical Hecke algebras in unramified setting, multiplicity estimate covers split tori. For we prove...

Abstract The local Langlands conjectures imply that to every generic supercuspidal irreducible representation of G 2 over a p -adic field, one can associate either PGSp 6 or PGL 3 . We prove this conjectural dichotomy, demonstrating precise correspondence between certain representations and other This arises from theta correspondences in E 7 , analysis Shalika functionals, spin L-functions.

The space of elliptic modular forms fixed weight and level can be identfied with a intertwining operators, from holomorphic discrete series representation SL2(R) to automorphic forms. Moreover, multiplying corresponds branching problem involving tensor products representations.

When $W$ is a finite Coxeter group acting by its reflection representation on $E$, we describe the category ${\mathsf{Perv}}_W(E_{\mathbb C}, {\mathcal{H}}_{\mathbb C})$ of $W$-equivariant perverse sheaves $E_{\mathbb C}$, smooth with respect to stratification hyperplanes. By using Kapranov and Schechtman's recent analysis hyperplane arrangements, find an equivalence categories from finite-dimensional modules over algebra given explicit generators relations. We also define equivariant affine...

In the 1990s, J. H. Conway published a combinatorial-geometric method for analyzing integer-valued binary quadratic forms (BQFs). Using visualization he named "topograph," revisited reduction of BQFs and solution Diophantine equations such as Pell's equation. It appears that crux his is coincidence between arithmetic group [Formula: see text] Coxeter type There are many groups, each may have unforeseen applications to arithmetic. We introduce Conway's topograph generalizations other groups....
