Axiomatization of geometry employing group actions

The aim of this paper is to develop a new axiomatization of planar geometry by reinterpreting the original axioms of Euclid. The basic concept is still that of a line segment but its equivalent notion of betweenness is viewed as a topological, not a metric concept. That leads quickly to the notion of connectedness without any need to dwell on the definition of topology. In our approach line segments must be connected. Lines and planes are unified via the concept of separation: lines are separated into two components by each point, planes contain lines that separate them into two components as well. We add a subgroup of bijections preserving line segments and establishing unique isomorphism of basic geometrical sets, and the axiomatic structure is complete. Of fundamental importance is the Fixed Point Theorem that allows for creation of the concepts of length and congruency of line segments. The resulting structure is much more in sync with modern science than other axiomatic approaches to planar geometry. For instance, it leads naturally to the Erlangen Program in geometry. Our Conditions of Homogeneity and Rigidity have two interpretations. In physics, they correspond to the basic tenet that independent observers should arrive at the same measurement and are related to boosts in special relativity. In geometry, they mean uniqueness of congruence for certain geometrical figures.Euclid implicitly assumes the concepts of length and angle measure in his axioms. Our approach is to let both of them emerge from axioms. Euclid obfuscates the fact that to compare lengths of line segments one needs rigid motions beforehand. Our system of axioms of planar geometry rectifies that defect of all current axiomatic approaches to planar geometry.Another thread of the paper is the introduction of boundary at infinity, an important concept of modern mathematics, and linking of Pasch Axiom to endowing boundaries at infinity with a natural relation of betweenness. That way spherical geometry can be viewed as geometry of boundaries at infinity.

“…Schumpeter [1912] who developed the model of the emergence of innovation is considered a forerunner in this field. Since then, innovations introduced by enterprises have been repeatedly defined and classified, with the emphasis on their character, type, phases of implementation, risks associated with conducting them, and the manner of management [Rogers, 1995;Schumpeter, 1985;Tidd, Bessant, 2021;Bogdanienko, 1998;Drucker, 1985;Unger, Zagler, 2000;Rothwell R, Gardiner, 1985;Bal-Woźniak, 2012;Trott, 2002;Ratajczak, 1995;Zajączkowski, 2003;Kordos, 2020]. All reports emphasise that the research and development process in the project is the key to the emergence of innovation.…”

Purpose – The objective of the article is to identify the factors affecting the use of R&D tax preferences in Poland. Research method – Qualitative and quantitative analysis, synthesis, deduction, induction, and inference by analogy. The study involved a group of 350 enterprises from the Lower Silesia Province in the high and medium-high technology sector and used the CATI survey methodology. The collected data was subjected to statistical analysis, including correlation and significance analysis. Results – The study investigates the reasons for not using tax preferences, the barriers to their use, and proposals of respondents (companies surveyed) regarding changes to the tax preferences. The main factors identified include appropriate organisation of R&D in the enterprise, cooperation with research entities, and knowledge of fiscal instruments supporting the development of R&D. Originality / value / implications / recommendations – Tax preferences (R&D tax relief and IP Box) are not used on a large scale and entrepreneurs say they have difficulty with using them. This study confirms that there are certain factors affecting the implementation of R&D and the use of tax preferences. So far, no attempt has been made to link the reasons for not using tax preferences, the barriers to their use, and the entrepreneurs’ proposals for changes so as to clearly identify the key factors affecting the use of effective legal solutions.
