On the foundations of inversion geometry [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1951
Introduction. A 3-dimensional inversion geometry over an ordered field V in which every nonnegative number is a square may be defined as a partially ordered set II of objects called points, circles, spheres, and inversion space with the properties: (i) if p is any point, then there is an affine geometry whose "points," "lines," "planes," and "3-space ...

Core foundations of abstract geometry [PDF]

open access: bronzeProceedings of the National Academy of Sciences, 2013
Human adults from diverse cultures share intuitions about the points, lines, and figures of Euclidean geometry. Do children develop these intuitions by drawing on phylogenetically ancient and developmentally precocious geometric representations that guide their navigation and their analysis of object shape?

Foundations of Algebraic Geometry [PDF]

open access: bronzeNature, 1948
ALGEBRAIC geometry, in spite of its beauty and importance, has long been reproached for lacking proper foundations. Great discoveries have been made, especially in Italy, by the intuition of a number of gifted workers, whose insight had been cultivated by a careful study of special cases.

Foundations of a nonlinear distributional geometry [PDF]

open access: greenActa Applicandae Mathematica, 2001
Co lombeau's construction of generalized functions (in its special variant) is extended to a theory of generalized sections of vector bundles. As particular cases, generalized tensor analysis and exterior algebra are studied. A point value characterization for generalized functions on manifolds is derived, several algebraic characterizations of spaces ...

Intellectual foundations of geometry in Islamic art [PDF]

open access: yesقرآن فرهنگ و تمدن, 2021
Islamic spiritual wisdom and mysticism has been formed in order to pay attention to the essence of God; the concepts of Islamic mysticism in the essence of the universe refer to the name "Allah Akbar" and the wisdom of using geometric codes and the ...

The influence of the shape of high-rise buildings on the design features and methods of making foundations in difficult soil conditions [PDF]

open access: yesE3S Web of Conferences, 2022
The methods of calculation and design of foundations considered in the article are applied in the construction of high-rise buildings of complex shape in heterogeneous soil conditions, leading in each case to minimizing costs.

Visual foundations of Euclidean geometry

open access: yesCognitive Psychology, 2021
Geometry defines entities that can be physically realized in space, and our knowledge of abstract geometry may therefore stem from our representations of the physical world. Here, we focus on Euclidean geometry, the geometry historically regarded as “natural”.
