Abstraction in Math and Superposition in QM

Abstraction turns equivalence into identity, but there are two ways to do it. The goal is to use the second notion of abstraction to shed some light on the notion of an inde…finite superposition in quantum mechanics.

Marcora Law for Europe

There is a time-tested solution in Spain and Italy that provides liquidity to such enterprises in a democratic manner by establishing employee ownership schemes. The new source of liquidity is allowing unemployed workers to capitalize part of their unemployment insurance to invest in a new or existing enterprise where they will have a job.

4Open: Special Issue: Intro. to Logical Entropy

4Open is a relatively new open access interdisciplinary journal (voluntary APCs) covering the 4 fields of mathematics, physics, chemistry, and biology-medicine. A special issue on Logical Entropy was sponsored and edited by Giovanni Manfredi, the Research Director of the CNRS Strasbourg. My paper is the introduction to the volume.

Book Draft: The Logic of Partitions

This book draft is an introduction to the logic of partitions on a set as well as the (quantum) logic of partitions (direct-sum decompositions or DSDs) on a vector space.

Book draft: Quantum Mechanics over Sets

Quantum mechanics overs sets (QM/ℤ₂ or QM/Sets) is a pedagogical or `toy’ model of finite-dimensional quantum mechanics (QM/ℂ) that reproduces in the simplified setting of vector spaces over ℤ₂ the essentials of projective measurements, the double-slit experiment, the indeterminacy principle, entanglement, Bell’s Theorem, the statistics of indistinguishable particles, and so forth,

Using ESOPs to Democratize Labor-Based Platforms

Our purpose is to propose another complementary approach, which is democratizing and adapting the Employee Stock Ownership Plan to gain co-ownership in the local subsidiaries of the labor-based platforms (LBP). This option puts a new tool in the hands of the municipal and national authorities that could regulate the platform sector.

Less-Known Supporters of Workplace Democracy

his paper, published as an editorial in the Journal for Participation and Employee Ownership collects together extensive quotations and extracts from 19th and 20th century thinkers who were little-known for being supporters of workplace democracy.
