Carnap's Geometrical Methodology

Journal for the History of Analytical Philosophy, 2023
In this paper, I will offer a novel perspective on Carnapian explication, understanding it as a philosophical analogue of the transfer principle methodology that originated in nineteenth-century projective geometry.

Cassirer and the Structural Turn in Modern Geometry

Journal for the History of Analytical Philosophy, 2018
The paper investigates Ernst Cassirer’s structuralist account of geometrical knowledge developed in his Substanzbegriff und Funktionsbegriff (1910). The aim here is twofold.

Idealizer Rings and Noncommutative Projective Geometry [PDF]

, 2004
We study some properties of graded idealizer rings with an emphasis on applications to the theory of noncommutative projective geometry. In particular we give examples of rings for which the $\chi$-conditions of Artin and Zhang and the strong noetherian ...

Projective geometry and spatial reasoning for STEM learning

Frontiers in Education
Projective geometry is a prominent area in many fields including art, design, architecture, and mathematics, but how it can contribute to children’s spatial reasoning as well as a supplementary geometry to that of Euclid’s in school mathematics curricula

Features of the geometry of the five-dimensional pseudo-Euclidean space of index two [PDF]

E3S Web of Conferences
The article is devoted to the study of the geometry of subspaces of a five-dimensional pseudo-Euclidean space. This space is attractive because all kinds of semi-Euclidean, semi-pseudo-Euclidean, hyperbolic three-dimensional spaces with projective ...

Note on the Projective Geometry of Paths.

Proceedings of the National Academy of Sciences of the United States of America, 1925
2. Projective Tensors. Theorems of the projective geometry of paths appear to have their statement in terms of what may be called projective tensors, i. e. tensors which are independent of the particular set of functions T\^ defining the paths.

Chemoresistome mapping in individual breast cancer patients unravels diversity in dynamic transcriptional adaptation

Molecular Oncology, EarlyView.
This study used longitudinal transcriptomics and gene‐pattern classification to uncover patient‐specific mechanisms of chemotherapy resistance in breast cancer. Findings reveal preexisting drug‐tolerant states in primary tumors and diverse gene rewiring patterns across patients, converging on a few dysregulated functional modules. Despite receiving the

Non-Projected Supermanifolds and Embeddings in Super Grassmannians

Universe, 2018
In this paper we give a brief account of the relations between non-projected supermanifolds and projectivity in supergeometry. Following the general results (L.

Analytic Projective Geometry

, 2014
Two general defects seem to be patent, one in presentation, one in range. I t is the author's aim to emphasize the force and directness of the analysis by having the results appear after a minimum of intermediate work, but this work has frequently been ...
