Not every object in the derived category of a ring is Bousfield equivalent to a module
Not every object derived category ring Bousfield equivalent module
2012/3/1
We consider the derived category of a specific non-Noetherian ring \Lambda, and show that there are objects in D(\Lambda) that are not Bousfield equivalent to any module. This answers a question posed...
Equivalent Semigroup Properties for Curvature-Dimension Condition
Curvature-dimension condition gradient inequality Harnack inequality
2011/2/28
Some equivalent gradient and Harnack inequalities of a diffusion semigroup are presented for the curvature-dimension condition of the associated generator. As ap-plications, the first eigenvalue, the ...
The algebras derived equivalent to gentle cluster tilted algebras
gentle algebras cluster tilted algebras derived equiva equivalence
2010/11/30
A cluster tilted algebra is known to be gentle if and only if it is cluster tilted of Dynkin type A or Euclidean type ˜A . We classify all finite dimensional algebras which are derived equivalent...
Two Mathematically Equivalent Versions of Maxwell's Equations
