Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：ANALYSIS AND APPROXIMATION OF FLUIDS UNDER SINGULAR FORCING
奇异强迫体 分析 近似 牛顿流体
2023/5/5
Motivated by applications, like modeling of thin structures immersed in a fluid, we develop a well posedness theory for Newtonian and some non-Newtonian fluids under singular forcing in Lipschitz doma...
QUANTITY “FORCING” AND EXCLUSION:BUNDLED DISCOUNTS AND NONLINEAR PRICING
FORCING EXCLUSION BUNDLED DISCOUNTS NONLINEAR PRICING
2015/9/23
Quantity “forcing” refers to pricing schemes that reward a buyer for purchasing some threshold quantity from a firm. When there are significant scale economies and buyers are unable to coordinate, eco...
INFERENCE OF IMPURITY RADIATIVE FORCING IN SNOW FROM MULTISPECTRAL TO HYPERSPECTRAL IMAGERS
soil moisture agriculture
2015/9/8
The inference of the radiative forcing of soot and dust in snow has taken on importance in recent years because of
the realization of the climate effects that they have (Hansen and Nazarenko, 2004). ...
Two models for the parametric forcing of a nonlinear oscillator
Parametric excitation Resonance Chaos Elliptic averaging
2015/8/27
Instabilities associated with 2:1 and 4:1 res-onances of two models for the parametric forcing of a strictly nonlinear oscillator are analyzed. The first model involves a nonlinear Mathieu equation an...

In this article I will analyze the impact of forcing with a measure algebra on various topological statements. In particular our interest will focus on the study of hereditary separability and the her...

PROPER FORCING CARDINAL ARITHMETIC UNCOUNTABLE LINEAR ORDERS
2015/8/17
In this paper I will communicate some new consequences of the Proper Forcing Axiom. First, the Bounded Proper Forcing Axiom implies that there is a well ordering of R which is Σ1-definable in (H(ω2), ...

The purpose of this paper is to present some results which suggest that the Singular Cardinals Hypothesis follows from the Proper Forcing Axiom. What will be proved is that a form of simultaneous refl...

2015/8/17
The Proper Forcing Axiom is a powerful extension of the Baire Category Theorem which has proved highly effective in settling mathematical statements which are independent of ZFC. In contrast to the Co...
The notes which follow reflect the content of a two day tutorial which took place at the Fields Institute on 5/29 and 5/30 in 2009. Most of the content has existed in the literature for some time (pri...
FORCING AXIOMS AND THE CONTINUUM HYPOTHESIS,PART II:TRANSCENDING ω1-SEQUENCES OF REAL NUMBERS
FORCING AXIOMS CONTINUUM HYPOTHESIS TRANSCENDING ω1-SEQUENCES OF REAL NUMBERS
2015/8/17
The purpose of this article is to prove that the forcing axiom for completely proper forcings is inconsistent with the Continuum Hypothesis. This answers a longstanding problem of Shelah.
One way to formulate the Baire Category Theorem is that no compact space can be covered by countably many nowhere dense sets. Soon after Cohen’s discovery of forcing, it was realized that it was natur...
Navy Operational Global Atmospheric Prediction System (NOGAPS): Forcing for Ocean Models
Atmospheric Prediction System Ocean Models
2015/7/31
Modeling the interactions between the atmosphere and ocean has become a very active research area in the meteorological and oceanographic communities in recent years. Several factors have contributed ...

Several attempts have been made in the past to construct encoding schemes that allow modularity to emerge in evolving systems, but success is limited. We believe that in order to create successful and...
Long-Term Impacts of Anthropogenic Forcing on the Black Sea Ecosystem
Anthropogenic Forcing Black Sea Ecosystem
2015/7/27
The Black Sea, a nearly enclosed and isolated environment, has suffered from severe ecological changes during the last three decades. It has been converted from an oligotrophic (less than 100 grams of...
Forcing and Dynamics of Seafloor-Water Column Exchange on a Broad Continental Shelf
Forcing and Dynamics Seafloor-Water Column Exchange Broad Continental Shelf
2015/7/22
Relict sediments of elevated permeability characterize the majority of continental shelves globally (Emery, 1968). In these settings, interactions between benthic boundary layer (BBL) flows and seabed...
