Warping Peirce Quincuncial Panoramas
The Peirce quincuncial projection is a mapping of the surface of a sphere to the interior of a square. It is a conformal mapping except for four points on the equator. These points of non-conformality cause significant artifacts in photographic applications. In this paper, we propose an algorithm and userinterface to mitigate these artifacts. Moreover, in order to facilitate an interactive user...
متن کاملThe Peirce translation
We develop applications of selection functions to proof theory and computational extraction of witnesses from proofs in classical analysis. The main novelty is a translation of minimal logic plus Peirce’s law into minimal logic, which we refer to as the Peirce translation, as it eliminates uses of Peirce’s law. When combined with modified realizability this translation applies to full classical...

متن کاملThe Logic of Peirce Algebras
Peirce algebras combine sets, relations and various operations linking the two in a unifying setting. This paper offers a modal perspective on Peirce algebras. Using modal logic a characterization of the full Peirce algebras is given, as well as a finite axiomatization of their equational theory that uses so-called unorthodox derivation rules. In addition, the expressive power of Peirce algebra...
متن کاملPeirce and Frege on Logic
Though Peirce and Frege played crucial roles in the development of modern logic, there has been so far little scholarly work comparing their positions on the nature of logic. I offer here a comparative study of their views on logic and I show that, although they developed their views independently from each other and with very different projects in mind, their positions are extremely similar (e...
