Integer factoring and compositeness witnesses

open access: yesJournal of Mathematical Cryptology, 2020
We describe a reduction of the problem of factorization of integers n ≤ x in polynomial-time (log x)M+O(1) to computing Euler’s totient function, with exceptions of at most xO(1/M) composite integers that cannot be factored at all, and at most x exp −cM ...

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

open access: yesComputer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

Establishing Shape Correspondences: A Survey

open access: yesComputer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

On primal and weakly primal ideals over commutative semirings

open access: yesGlasnik matematički, 2008
Since the theory of ideals plays an important role in the theory of semirings, in this paper we will make an intensive study of the notions of primal and weakly primal ideals in commutative semirings with an identity 1. It is shown that these notions inherit most of the essential properties of the primal and weakly primal ideals of a commutative ring ...

Partitions of numbers and the algebraic principle of Mersenne, Fermat and even perfect numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Let ρ be an odd prime greater than or equal to 11. In a previous work, starting from an M-cycle in a finite field 𝔽_ρ, it has been established how the divisors of Mersenne, Fermat and Lehmer numbers arise.

Beyond Immediate Givenness: Husserl's Content‐Apprehension Schema in Light of Merleau‐Ponty's Critique of Sensation

open access: yesEuropean Journal of Philosophy, EarlyView.
Abstract Merleau‐Ponty's Phenomenology of Perception (2012 [1945]) opens with a detailed critique of traditional philosophical accounts of sensation, generally understood as having Husserl's “content‐apprehension schema” among its targets. The schema sees perception as resulting from the interpretation (“apprehension” or “apperception”) of “raw ...

Retrieving Your Concepts: Iris Murdoch on Original Sin

open access: yesEuropean Journal of Philosophy, EarlyView.
Abstract In The Sovereignty of Good, Iris Murdoch argues that our moral thinking will be impoverished until it possesses a secular conception of original sin. Such a notion would need to remove unacceptable Christian baggage while retaining a genuine claim to be a descendant of the original Christian concept.

The aesthetic sublime of megaproject structures: A framework and a research agenda

open access: yesEuropean Management Review, EarlyView.
Abstract The physical structures of megaprojects—such as mega‐canals, metros, railway lines, bridges, tunnels, and iconic opera houses—hold a profound capacity to generate aesthetic experiences with enduring societal impact. Yet, research on megaprojects has predominantly focused on functionality and economic rationale with aesthetics being pushed to ...
