Adjoint relations for the category of local dcpos [PDF]
Categories and General Algebraic Structures with Applications, 2017 In this paper, we consider the forgetful functor from the category {bf LDcpo} of local dcpos (respectively, {bf Dcpo} of dcpos) to the category {bf Pos} of posets (respectively, {bf LDcpo} of local dcpos), and study the existence of its left and right ...

Bordism groups of solutions to differential relations
, 2009 In terms of category theory, the Gromov homotopy principle for a set valued functor $F$ asserts that the functor $F$ can be induced from a homotopy functor. Similarly, we say that the bordism principle for an abelian group valued functor $F$ holds if the

On the Derived Functors of the Third Symmetric-Power Functor
Tbilisi Mathematical Journal, 2009 We compute the derived functors of the third symmetric-power functor and their cross-effects for certain values. These calculations match predictions by the first named author and largely prove them in general.

The family Floer functor is faithful [PDF]
, 2014 Family Floer theory yields a functor from the Fukaya category of a symplectic manifold admitting a Lagrangian torus fibration to a (twisted) category of perfect complexes on the mirror rigid analytic space.

由度量空间诱导的*-拓扑和s-拓扑(* -Topology and s-topology induced by metric space)
Zhejiang Daxue xuebao. Lixue ban, 2018 This paper studies * -topology and s-topology in polysaturated nonstandard model,which are induced by metric space on two nonstandard sets. In order to construct * -topology , the set of finite points is introduced.

Forum of Mathematics, Pi, 2023 We define, for each quasisyntomic ring R (in the sense of Bhatt et al., Publ. Math. IHES 129 (2019), 199–310), a category $\mathrm {DM}^{\mathrm {adm}}(R)$ of admissible prismatic Dieudonné crystals over R and a functor from p-divisible groups ...

Advances in Mathematics, 1998 The purpose of the paper is to explain the general theory of coherent functors on the category of finitely generated modules over a noetherian ring \(A\), and to give some applications to cohomology of coherent sheaves on projective spaces. In the special case where \(A\) is a discrete valuation ring, a necessary and sufficient condition for a functor ...

Sliding Functor and Polarization Functor for Multigraded Modules [PDF]
Communications in Algebra, 2012 We define "sliding functors", which are exact endofunctors of the category of multi-graded modules over a polynomial ring. They preserve several invariants of modules, especially the (usual) depth and Stanley depth. In a similar way, we can also define the "polarization functor".

3D MR Thermometry Using Bi‐Directional Segmented EPI for Transcranial‐Focused Ultrasound
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To evaluate the feasibility of replacing clinically utilized 2D thermometry with 3D segmented EPI‐based thermometry with equivalent accuracy, precision, and scan time. Methods A 3D segmented EPI (segEPI) trajectory was modified to allow readouts along both the forward and reverse direction for each phase encoding line, and the sequence

Neat embeddings as adjoint situations
, 2013 We view the neat reduct operator as a functor that lessens dimensions from CA_{\alpha+\omega} to CA_{\alpha} for infinite ordinals \alpha. We show that this functor has no right adjoint. Conversely for polyadic algebras, and several reducts thereof, like
