Singular points of the polarization tensor
Solar Physics, 1996The problem to compute the magnetic field above the chromosphere using data of the vector τ = B t /B t that gives the projected field direction can be solved with different approximations. The field of direction vectors τ is, however, not the only field accessible to observations. The Stokes parameters, which are components of the radiation tensor, can

Flattening a non-degenerate CR singular point of real codimension two
, 2017This paper continues the previous studies in two papers of Huang–Yin [HY16,HY17] on the flattening problem of a CR singular point of real codimension two sitting in a submanifold in $${{\mathbb {C}}^{n+1}}$$Cn+1 with n + 1 ≥ 3, whose CR points are non ...

We study the limit behavior of a sequence of Markov processes whose distributions outside any neighborhood of a “singular” point are attracted to a certain probability law. In any neighborhood of this point, the limit behavior can be irregular.

Point Counting on Singular Hypersurfaces
2008Let q = p r be a prime power. Let Open image in new window be a homogenous polynomial of degree d. Let Open image in new window be the hypersurface defined by Open image in new window . A natural question to ask is how to determine Open image in new window .

Summability Tests for Singular Points
Canadian Mathematical Bulletin, 1972King [5] devised two tests for determining when z = 1 is a singular point of the function f(z) defined by1having radius of convergence equal to one. The point z = 1 and radius of convergence one may be chosen without loss of generality.

Nonlinear Analysis: Real World Applications, 2011
The authors give two recursive formulas to obtain the singular quantities to know when a singular point of a complex analytic system with linear part \(z'=z\), \(w'=-w\) is integrable. One is obtained searching for obstructions to have a formal first integral and the other one is obtained searching for conditions to have an integrating factor that does
