On compactly generated torsion pairs and the classification of co-t-structures for commutative noetherian rings [PDF]
, 2014 We classify compactly generated co-t-structures on the derived category of a commutative noetherian ring. In order to accomplish that, we develop a theory for compactly generated Hom-orthogonal pairs (also known as torsion pairs in the literature) in ...

Convergent Homotopy Analysis Method for Solving Linear Systems
Advances in Numerical Analysis, Volume 2013, Issue 1, 2013., 2013 By using homotopy analysis method (HAM), we introduce an iterative method for solving linear systems. This method (HAM) can be used to accelerate the convergence of the basic iterative methods. We also show that by applying HAM to a divergent iterative scheme, it is possible to construct a convergent homotopy‐series solution when the iteration matrix G

SAORES: a spatially explicit assessment and optimization tool for regional ecosystem services [PDF]
Landscape Ecology, 2014 The concept of ecosystem services (ES) has become mainstreamed in environmental planning and management recently, and with that various tools for quantifying ecosystem services have emerged. However, designing the tools for integrated assessment and optimization of multiple ES has become a challenging task.

On some extensions of the accelerated overrelaxation (AOR) theory
International Journal of Mathematics and Mathematical Sciences, Volume 5, Issue 1, Page 49-60, 1982., 1981 This paper extends the convergence theory of the Accelerated Overrelaxation (AOR) method to cases analogous to those considered first by Ostrowski and then by Varga in connection with the Successive Overrelaxation (SOR) method. Among others, the Ostrowski Theorem, some of the theorems by Varga on the extensions of the SOR theory, and some recent ...

A Bayesian Clearing Mechanism for Combinatorial Auctions
, 2018 We cast the problem of combinatorial auction design in a Bayesian framework in order to incorporate prior information into the auction process and minimize the number of rounds to convergence.

Derived equivalences induced by big cotilting modules [PDF]
, 2014 We prove that given a Grothendieck category G with a tilting object of finite projective dimension, the induced triangle equivalence sends an injective cogenerator of G to a big cotilting module.

The accelerated SAOR method for large linear systems
Journal of Computational and Applied Mathematics, 1988 Sei A eine symmetrische und positiv definite Matrix. Zur Lösung von \(Ax=b\) wird ein dreiparametriges Verfahren vorgeschlagen, dessen Parameter sich im Verlauf des Verfahrens selbst korrigieren. Basis ist ein symmetrisches, extrapoliertes SOR-Verfahren, welches als Grundlage eines semi-iterativen Verfahrens genommen wird.

Tubal ligation and endometrial Cancer risk: a global systematic review and meta-analysis
BMC Cancer, 2019 Background Studies on relationship between tubal ligation and endometrial cancer have led to contradictory findings. In several studies, however, a reduced endometrial cancer risk was suggested following tubal ligation. Therefore, a systematic review and
