Abstract:
Let A be a C∗-algebra with stable rank one and real rank zero. In this paper, it is shown that the usual distance dU defined on the approximate unitary equivalence classes (or unitary orbits) of the positive elements in A is equal to the distance dW defined on morphisms from Cuntz semigroup of C0(0,1] to the Cuntz semigrout of A.

Abstract:
AbstractWe study certain symplectic quotients of n-fold products of complex projective m-space by the unitary group acting diagonally. After studying nonemptiness and smoothness of these quotients we construct the action-angle variables, defined on an open dense subset, of an integrable Hamiltonian system. The semiclassical quantization of this system reporduces formulas from the representation theory of the unitary group.

Abstract:
We generalize bounds of Liu–Wan–Xiao for slopes in eigencurves for definite unitary groups of rank $2$ to slopes in eigenvarieties for definite unitary groups of any rank. We show that for a definite unitary group of rank $n$ , the Newton polygon of the characteristic power series of the $U_p$ Hecke operator has exact growth rate $x^{1+2/{n(n-1)}}$ , times a constant proportional to the distance of the weight from the boundary of weight space. The proof goes through the classification of forms associated to principal series representations. We also give a consequence for the geometry of these

Abstract:
Discusses certain one-parameter subgroups of the low-rank unitary groups called root subgroups. Unitary groups also have representations of Lie type which means they consist of transformations that act as automorphisms of an underlying Lie algebra, in this case the special linear algebra. Exploring this definition of the unitary groups, we find a correlation, via exponentiation, to the basis elements of Lie algebra.

Abstract:
Within the fields of electoral studies and legislative politics, the interest of this study is the Brazilian electoral system and the unity of the parties it produces. Specifically, I ask how post-electoral intraparty rank affects party unity. I determine post-electoral intraparty rank by comparing deputies’ vote share of the total national vote count. By compiling a database of 48 roll-call votes of 37 Federal Deputies from São Paulo, I compare how often the deputies toe the party line to their vote share. I also test for the geographical concentration of votes in cases where I find it relev

What does spirituality mean in Judaism? What is prayer and does it work? Prayer is a vital concern in Judaism, and one of the major forms in which spirituality is expressed. Equal in rank, or perhaps even higher, is learning. ‘The spiritual life—prayer, meditation, Torah’ considers the place of spirituality in Jewish worship. The most universal, accessible, and distinctive form of Jewish spirituality is Torah study. Learning the Torah is an expression of love that spans over generations. It is a unity of souls. It unites those who hand it down with those who receive it.

This chapter clarifies how the impulse to close ranks raised concerns about the prioritizing of the collective over the individual. Black collectivity is expressed as kinship in the nationalist imagination, so there is an overriding anxiety about metaphors of family, which assume an intimacy or affiliation that might not be present. The chapter then examines texts informed by nationalism that challenge this investment in kinship. These include John A.

This chapter tracks how artists inhabit the subjective space of whiteness as a closing ranks move. This idea may seem counterintuitive, but for many thinkers, exploring whiteness is useful in determining the conventional parameters of Black identity. The act of identifying and challenging these boundaries creates the opportunity for imagining a unity not plagued by restrictive conceptions of blackness. Therefore, turning inward does not appear as a mere rejection of whiteness in favor of shoring up blackness. The chapter then highlights how the rhetoric of White innocence provides the foundati
