We develop a formal ontology within the four dimensionalist (4D) paradigm by showing how the algebraic description of spatial mereotopology – a Boolean algebra equipped with a connection relation – can be enriched to provide a mereotopology in which the entities are spatio-temporal, rather than spatial, regions. With the 4D approach it is natural to identify a period of time with all of space d...

Three experiments examined adult humans' folk physics (i.e., their naturally occurring understanding of the physical world) using variations of rope-and-banana problems that are used to study chimpanzees' folk physics. When presented with symbolic versions of these problems, the participants' choices were controlled by both the presence of a physical connection between a tool and reward (unlike...

This article lays out six propositions centering on a relationship between people-place connections and strategic behavior in natural resource politics. The first two propositions suggest a strong and direct connection between self-identity, place, and how individuals perceive and value the environment. The third, fourth, and fifth propositions tie together social group identity and place, part...

This paper investigates a connection between the ordering ⊳∗ among theories in model theory and the (N)SOPn hierarchy of Shelah. It introduces two properties which are natural extensions of this hierarchy, called SOP2 and SOP1, and gives a connection between SOP1 and the maximality in the ⊳∗-ordering. Together with the known results about the connection between the (N)SOPn hierarchy and the exi...

Evolutionary algorithms(EAs) have been applied to designing and training artiicial neural net-works(ANNs), independently or in various combinations with other algorithms like back propagation and simulated annealing, which can be distinguished into the evolution of connection weights, of architectures and of learning rules. In this paper, we present an evolutionary approach to designing neural ...

This paper explores which classes of graphs and matroids are k-balanced. A connection between k-balanced graphs and k-balanced matroids was also obtained. In this paper, we continue our study of the class of k-balanced matroids in order to see what matroid operations preserve k-balance. Since strong maps of matroids are defined as analogues of continuous maps of topological spaces, it is natura...

In recent papers [1, 2] I have argued that the observed cosmological acceleration can be accounted for by the inclusion of a 1/R term in the gravitational action in the Palatini formalism. Subsequently, Flanagan [3, 4] argued that this theory is equivalent to a scalar-tensor theory which produces corrections to the standard model that are ruled out experimentally. In this article I examine the ...

In abstract Yang–Mills theory the standard instanton construction relies on the Hodge star having real eigenvalues which makes it inapplicable in the Lorentzian case. We show that for the affine connection an instanton-type construction can be carried out in the Lorentzian setting. The Lorentzian analogue of an instanton is a spacetime whose connection is metric compatible and Riemann curvature...

LetG be a connected affine algebraic reductive group over C. Let P be a holomorphic principal G bundle on M (i.e. the transition functions of P are holomorphic). Assume that P admits a holomorphic connection D compatible with the holomorphic structure. This means the following : D is a holomorphic 1-form on P with values in the Lie algebra, g, of G, such that D is invariant for the action of G ...
