Zeta functions of singular curves over finite fields [PDF]

, 1997
Let X be a complete, geometrically irreducible, algebraic curve defined over a finite field Fq and let (X ,t) be its zeta function [Ser1]. If X is a singular curve, two other zeta functions exist.

Singular integral operators associated to curves with rational components [PDF]

, 2008
We prove L-p(R-n),1 < p < infinity, bounds for[GRAPHICS]and[GRAPHICS]where R-j(t) = P-j(t)/Q(j)(t),j = 1,2...,n, are rational functions. Our bounds depend only on the degrees of the polynomials P-j, Q(j) and, in particular, they do not depend on ...

Construction of nonsingular formulae of variance and covariance function of disturbing gravity gradient tensors

Geodesy and Geodynamics, 2013
When the computational point is approaching the poles, the variance and covariance formulae of the disturbing gravity gradient tensors tend to be infinite, and this is a singular problem.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

On Certain Initial Techniques to Model Singular Functions

Global Integrated Mathematics
Nowadays many researches are devoted to pathological mathematical objects of real analysis such as the Moran and Cantor-like fractal sets, functions with complicated local structure, as well as their generalizations and various applications. For example,

On some automorphic properties of Galois traces of class invariants from generalized Weber functions of level 5

Open Mathematics, 2019
After the significant work of Zagier on the traces of singular moduli, Jeon, Kang and Kim showed that the Galois traces of real-valued class invariants given in terms of the singular values of the classical Weber functions can be identified with the ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...
