We describe CW complexes for complex projective algebraic surfaces in the context of practical computation of topological invariants. CW COMPLEXES FOR COMPLEX ALGEBRAIC SURFACES

Abstract: The classifying space E(Γ,F) for a family F of subgroups of a group Γ is defined up to Γ-homotopy as a Γ-CW -complex E(Γ,F) such that E(Γ,F) is contractible if H belongs to F and is empty otherwise. We investigate the question whether there is a finite-dimensional Γ-CW -model, a finite Γ-CW -model or a Γ-CW -model of finite type for E(Γ,F) focusing on the case where F is the family of...

Anti Cw antibody is a low frequency immunoglobulin (IgG) against red cell antigen- Cw. It is clinically significant and may cause haemolytic disease of the newborn. Due to its low frequency, it is not included in routine antenatal antibody screening panel. The incidence of Anti Cw antibodies has not been reported in our population. Here, we describe the clinical and laboratory spectra of three ...

We report the development of a continuous wave cavity ring-down spectroscopic (CW-CRDS) diagnostic for real-time, in situ measurement of velocity distribution functions of ions and neutral atoms in plasma. This apparatus is less complex than conventional CW-CRDS systems. We provide a detailed description of the CW-CRDS apparatus as well as measurements of argon ions and neutrals in a high-densi...

The $\mathrm{K}$-cowaist $\text{K-cw}_2 (M)$ and the $\hat{\mathsf{A}}$-cowaist $\hat{\mathrm{A}}$-$\mathrm{cw}_2 are two interesting invariants on a manifold $M$, which closely related to existence of positive scalar curvature metric $M$. In this note, we give detailed proof following inequality due Gromov: (M) \le c \hat{\mathrm{A}}$-$\mathrm{cw}_2 (M)$, where $c$ is dimensional constant.
