Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Convex sets with Oka complements
Oka补 凸集 Oka流形
2023/11/29
It is now known that the complement of any polynomially convex compact set K in C^n is an Oka manifold. In particular this holds if K is convex. I will discuss a recent result, joint with Forstneri?, ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Substitutes and Complements
替代条件 离散经济体 竞争均衡
2023/4/18
It is well known that the substitutes condition plays a key role in guaranteeing the existence of competitive equilibrium in discrete economies. It also brings useful structure to equilibria, and enge...
Adverbial Quantification over (Interrogative) Complements
Complements Adverbial Quantification
2015/9/2
This paper rejects Berman’s 1991 theory of QV and supports that of
Utpal Lahiri (1991, 1998). Berman takes QV to be quantification over the
WH variable in the interrogative, as suggested by the form...
Spare Me the Complements: An Immoderate Proposal for Eliminating the "We/They" Category Boundary
category learning uncomplemented categories early experience socialization critical period ethnocentrism we they distinction
2015/8/3
A speculative hypothesis about how to eliminate the "we/they" distinction by rearing children (during early critical years) in "aggregates in flux" instead of in kinship-based families: A category can...
This paper considers the optimal selling mechanism for complementary items.
When buyers are perfectly symmetric, the optimal procedure is to bundle the items
and run a standard auction. In general, ...
Are Efficiency and Equity in School Finance Substitutes or Complements?
Education finance dramatic finance
2015/7/20
since desegregation, the most important changes to American elementary and secondary schooling have almost certainly been in the realm of school finance. This is not only because dramatic changes have...
On the Permanents of Complements of the Direct Sum of identity Matrices
Complement, permanent magnet straight, identity matrix

On the Permanents of Complements of the Direct Sum of identity Matrices.
In Cournot's model of complements, the producers of A and B are both monopolists. This paper extends Cournot's model to allow for competition between complements on one side of the market. Consider tw...
A connection between the bipartite complements of line graphs and the line graphs with two positive eigenvalues
line graphs graph spectra complements Courant-Weyl inequalities
2012/4/16
In 1974 Cvetkovi\'c and Simi\'c showed which graphs $G$ are the bipartite complements of line graphs. In 2002 Borovi\'canin showed which line graphs $L(H)$ have third largest eigenvalue $\lambda_3\leq...
We make some remarks on the foundations of the homotopy theory of enriched precategories, as exposed in Carlos Simpson's book "Homotopy theory of higher categories".
Cofinitely Hopfian groups, open mappings and knot complements
Cofinitely Hopfian open mappings relatively hyperbolic
2011/1/19
A group is defined to be cofinitely Hopfian if every homomorphism → whose image is of finite index is an automorphism.Geometrically significant groups enjoying this pr...
Contact Homology of Orbit Complements and Implied Existence
Contact Homology of Orbit Complements Implied Existence
2011/1/19
For Reeb vector elds on closed 3-manifolds, cylindrical contact homology is used to show that the existence of a set of closed Reeb orbit with certain knotting/linking properties implies the existenc...
On complements and the factorization problem for Hopf algebras
Normal Hopf subalgebras Semi-direct product
2011/1/20
Two new results concerning complements in a semisim-ple Hopf algebra are proved. They extend some well known results from group theory. The uniqueness of Krull Schmidt Remak type
decomposition is pro...
IS COGNITIVE GRAMMAR A USAGE-BASED MODEL? TOWARDS A REALISTIC ACCOUNT OF ENGLISH SENTENTIAL COMPLEMENTS
Cognitive Grammar usage-based sentential complementation empirical support iconicity
2009/10/19
Cognitive Grammar (Langacker FCG1, FCG2) is commonly described as a usagebased model, a label applied to grammatical approaches which purport to give "substantial importance to the actual use of the l...
