Application of singularity theory and logistic regression model for tungsten polymetallic potential mapping [PDF]

Nonlinear Processes in Geophysics, 2013
Geo-anomalies with complex structures in the earth's crust may be defined as preferable hydrothermal ore-forming targets. The separation and explanation of anomaly from geological background have a profound influence on the analysis of geological ...

Igusa's p-adic local zeta function and the Monodromy Conjecture for non-degenerated surface singularities [PDF]

, 2013
In 2011 Lemahieu and Van Proeyen proved the Monodromy Conjecture for the local topological zeta function of a non-degenerated surface singularity. We start from their work and obtain the same result for Igusa's p-adic and the motivic zeta function.

Beyond the average: Detecting global singular nodes from local features in complex networks [PDF]

EPL (Europhysics Letters), 2009
Deviations from the average can provide valuable insights about the organization of natural systems. The present article extends this important principle to the systematic identification and analysis of singular motifs in complex networks. Six measurements quantifying different and complementary features of the connectivity around each node of a ...

Milnor fibers and Links of Local Complete Intersections [PDF]

, 2014
We discuss and prove a number of cohomological results for Milnor fibers, real links, and complex links of local complete intersections with singularities of arbitrary dimension.Comment: 14 ...

A Parametric Shape Model Applied to Tracing the Migration of the Objects Near an Asteroid

Earth and Space Science, 2021
In the past decades, space missions to small bodies (Galileo, OSIRIS‐REx, Hayabusa, Hayabusa2, Chang'e 2, Rosetta, etc.) have enriched us greatly with voluminous new knowledge on our solar system.

Codimension-3 Singularities and Yukawa Couplings in F-theory [PDF]

, 2009
F-theory is one of the frameworks where all the Yukawa couplings of grand unified theories are generated and their computation is possible. The Yukawa couplings of charged matter multiplets are supposed to be generated around codimension-3 singularity ...

Convergence analysis of energy conserving explicit local time-stepping methods for the wave equation [PDF]

, 2017
Local adaptivity and mesh refinement are key to the efficient simulation of wave phenomena in heterogeneous media or complex geometry. Locally refined meshes, however, dictate a small time-step everywhere with a crippling effect on any explicit time ...

Hodge–Lyubeznik numbers

Comptes Rendus. Mathématique
We define a Hodge-theoretical refinement of the Lyubeznik numbers for local rings of complex algebraic varieties. We prove that these numbers are independent of the choices made in their definition and that, for the local ring of an isolated singularity,

Classification of rational unicuspidal curves with two Newton pairs [PDF]

, 2015
Based on Tiankai Liu's PhD thesis (MIT, 2014), we give a complete classification of local topological types of singularities with two Newton pairs on rational unicuspidal complex projective plane curves.

Complex Wrinkle Field Evolution

ACM Transactions on Graphics, 2023
We propose a new approach for representing wrinkles, designed to capture complex and detailed wrinkle behavior on coarse triangle meshes, called Complex Wrinkle Fields.
