Abstract Let $\mathcal {A} \subset{\mathcal {B}}(\mathcal {H})$ A ⊂ B ( H ) be a row contraction and $\Phi _{\mathcal {A}}$ Φ determined by {A}$ completely positive map on ${\mathcal . ...

We show that if a holomorphic n-dimensional compact torus action on a compact connected complex manifold of complex dimension n has a fixed point then the manifold is equivariantly biholomorphic to a smooth toric variety.

Key Practice Points: • Upper limb entrapment neuropathies can present clinically similar to various musculoskeletal conditions. • History, physical examination, and electrodiagnostic studies alone do not always accurately identify the correct diagnosis. • The practioner’s ability to employ a combination of neuromuscular and musculoskeletal ultrasound can be a powerful adjuvant to clinical and e...

The paper presents a topology-based visualization method for time-dependent two-dimensional vector fields. A time interpolation enables the accurate tracking of critical points and closed orbits as well as the detection and identification of structural changes. This completely characterizes the topology of the unsteady flow. Bifurcation theory provides the theoretical framework. The results are...
