Du topos à la contre-topique. Cartographie du magique comme champ opératoire de la phénoménologie sartrienne

open access: yesMethodos, 2015
This article questions the status of the magical in early Sartre both as an inheritage of the reading of french psychology and anthropology and as the place of the phenomenological break by which an original philosophy of existence can be developped. The

A remark on the existence of positive radial solutions to a Hessian system

open access: yesAIMS Mathematics, 2021
We give new conditions for the study of existence of positive radial solutions for a system involving the Hessian operator. The solutions to be obtained are given by successive-approximation.

Existence of Universal Entangler [PDF]

open access: yes, 2007
A gate is called entangler if it transforms some (pure) product states to entangled states. A universal entangler is a gate which transforms all product states to entangled states.

Cauchy problem of the generalized Zakharov type system in R 2 $\mathbf{R}^{2}$

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we consider the initial value problem for a two-dimensional generalized Zakharov system with quantum effects. We prove the existence and uniqueness of global smooth solutions to the initial value problem in the Sobolev space through making

Schelling’s Criticism of Ontological Argument and Interpretation of Kant’s Doctrine of the Ideal of Reason

open access: yesКантовский сборник, 2021
To reconstruct a critique of the ontological proof of the existence of God in Schelling’s philosophy I examine his interpretation of the ontological argument by Anselm of Canterbury and Descartes as well as Schelling’s assessment of the critique of the ...

Existence and non-existence of Blow-up solutions for a non-autonomous problem with indefinite and gradient terms [PDF]

open access: yes, 2014
We deal with existence and non-existence of non-negative entire solutions that blow-up at infinity for a quasilinear problem depending on a non-negative real parameter. Our main objectives in this paper are to provide far more general conditions for existence and non-existence of solutions.

On the Existence and Stability of Bulk Nanobubbles.

open access: yesLangmuir, 2018
Bulk nanobubbles are a novel type of nanoscale bubble system. Because of their extraordinary behavior, however, their existence is not widely accepted.

Existence of moduli spaces for algebraic stacks [PDF]

open access: yesInventiones Mathematicae, 2018
We provide necessary and sufficient conditions for when an algebraic stack admits a good moduli space and prove a semistable reduction theorem for points of algebraic stacks equipped with a Θ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage ...

Existence and structure of P-area minimizing surfaces in the Heisenberg group [PDF]

open access: yesarXiv, 2021
We study existence and structure of $P-$area minimizing surfaces in the Heisenberg group under Dirichlet and Neumann boundary conditions. We show that there exists an underlying vector field $N$ that characterized existence and structure of $P$-area minimizing surfaces. This vector field exists even if there is no $P$-area minimizing surface satisfying

Einstein solvmanifolds: existence and non-existence questions

open access: yes, 2010
The general aim of this paper is to study which are the solvable Lie groups admitting an Einstein left invariant metric. The space N of all nilpotent Lie brackets on R^n parametrizes a set of (n+1)-dimensional rank-one solvmanifolds, containing the set ...
