Notions of Anonymous Existence in Martin-L\"of Type Theory [PDF]
As the groupoid model of Hofmann and Streicher proves, identity proofs in intensional Martin-L\"of type theory cannot generally be shown to be unique. Inspired by a theorem by Hedberg, we give some simple characterizations of types that do have unique ...

Stability Results for a Coupled System of Impulsive Fractional Differential Equations
In this paper, we establish sufficient conditions for the existence, uniqueness and Ulam−Hyers stability of the solutions of a coupled system of nonlinear fractional impulsive differential equations. The existence and uniqueness results are carried

A comparative Study of Predicating the Essence and the Flimsy from the Viewpoint of Mulla Sadra and Ibn Arabi [PDF]
Predicating the Essence and the Flimsy is one of Mulla Sadra's important innovations. The implication of this theory is that imperfect existence in perfect existence is more fully realized, so that the higher order encompasses all the lower perfections ...

On an Existence Lemma in Valuation Theory [PDF]
Recently one of the writers used, in proving a theorem on the commutativity of certain division rings, the following lemma :I. Let L be a field and K be its proper subfield. Except either when L is of characteristic p ≠ O and absolutely algebraic or ivhen L is algebraic and purely inseparable over K, there exists a pair of distinct (special exponential)

The Stability of Parabolic Problems with Nonstandard p(x, t)-Growth
In this paper, we study weak solutions to the following nonlinear parabolic partial differential equation ∂ t u − div a ( x , t , ∇ u ) + λ ( | u | p ( x , t ) − 2 u ) = 0 in Ω T , where λ ≥ 0 and ∂ t u denote ...

Ontological Evaluation of the Theory of Eexplaining Plurality in Mulla Sadra's Unificationist System [PDF]
Mulla Sadra has based his philosophical system on a number of principles, which will have important implications for each of them; the most important of which is the "Originality of Being", whose belief will lead to the adoption of the well-known theory ...

Explanation of Stephen Hawking’s fallacy of the Big Bang Theory and denial of the existence of God [PDF]
Hawking emphasizes the big bang theory as a practical theory, thus answering the question of how the universe began. It has been emphasized by Stephan Hawking.

Fractal–Fractional Analysis of a Water Pollution Model Using Fractional Derivatives
Water pollution is a significant threat for human health, particularly in developed countries. This study advances the mathematical understanding of WP transmission dynamics by developing a fractional–fractal derivative framework with non-singular ...
