论文摘要
情境长期以来一直与拓扑特性有关。在这项工作中,在广义上下文的更广泛的框架中,这种关系被提升为身份证明。我们将状态,效应和转换通常用作向量空间中的向量,并将其编码为切线空间,从而使非上下文条件的通用条件使离散的闭合路径表示无效的估值中,这立即扩展到连续情况。情境行为接受了这种形式主义中的两个同等解释。在称为“schrödinger”的几何或内在的现实观点中,施加了平坦的空间,导致上下文行为被表达为概率函数的非平凡的全体性,类似于电磁张量。作为估值函数的修改,我们使用等效曲率将上下文与干扰,非交易性和签名度量联系起来。从称为“海森堡”的拓扑或参与式观点中,估值功能必须满足经典的公理,从而导致需要在事件中拓扑缺陷中表达的上下文行为,从而导致非平凡的单片。我们利用此类缺陷将上下文与非委托女联系起来并构建广义Vorob'ev定理,这是关于非上下文性的必然性的结果。在这种形式主义中,我们确定了具有结果确定性模型的上下文分数,以及在本体论模型中解决干扰的途径,作为非平凡的过渡图。我们还讨论了编码上下文性的两个观点与量子理论的解释如何相关。
Contextuality has long been associated with topological properties. In this work, such a relationship is elevated to identification in the broader framework of generalized contextuality. We employ the usual identification of states, effects, and transformations as vectors in a vector space and encode them into a tangent space, rendering the noncontextual conditions the generic condition that discrete closed paths imply null phases in valuations, which are immediately extended to the continuous case. Contextual behavior admits two equivalent interpretations in this formalism. In the geometric or intrinsic-realistic view, termed "Schrödinger", flat space is imposed, leading to contextual behavior being expressed as non-trivial holonomy of probabilistic functions, analogous to the electromagnetic tensor. As a modification of the valuation function, we use the equivalent curvature to connect contextuality with interference, noncommutativity, and signed measures. In the topological or participatory-realistic view, termed "Heisenberg", valuation functions must satisfy classical measure axioms, resulting in contextual behavior needing to be expressed in topological defects in events, resulting in non-trivial monodromy. We utilize such defects to connect contextuality with non-embeddability and to construct a generalized Vorob'ev theorem, a result regarding the inevitability of noncontextuality. We identify in this formalism the contextual fraction for models with outcome-determinism, and a pathway to address disturbance in ontological models as non-trivial transition maps. We also discuss how the two views for encoding contextuality relate to interpretations of quantum theory.
