The phrase "a proof for existence" is not correct in standard English; it should be "a proof of existence." You can use it when discussing evidence or arguments that demonstrate the existence of something, often in philosophical or scientific contexts.
Example: "The discovery of ancient artifacts serves as a proof of existence for the civilization that once thrived in this region."
Alternatives: "evidence of existence" or "demonstration of existence."
Dufwenberg and Kirchsteiger (2004) showed that extending the concept of reciprocity for dynamic games does not allow for a proof of existence using backward induction, given that the best action of each player at each history not only depends on the strategy of the other players, but also on the actions of the same player at other histories.
A proof for the existence of at least one truth in itself, i.e., a true proposition, requires premise (2).
Thus, if we take the derivation as a proof for the existence of at least one true proposition, we will succumb to an obvious petitio principii.
First, it provides a proof for the existence of God by perfection, as the most intense limit case, given that simplicity is an attribute of perfection.
Immediately after her discussion of her first principles of knowledge, Du Châtelet also turns to metaphysical first principles that can be derived from the epistemology, and she too turns to a proof for the existence and nature of God.
For Allen Cahn equation u_{t}=u_{xx}+u 1-u) (u-a), with (ain(0,1)), as a special example in [10], Fukao et al. in [11] gave a proof for the existence of entire solutions by using the explicit expression of the traveling front and the comparison theorem.
Finally, Thomas Bayes wrote an essay discussing theological implications of de Moivre's results: his solution to a problem, namely that of determining the probability of an event by its relative frequency, was taken as a proof for the existence of God by Bayes.
This paper is the result of the author's attempt to answer these questions and gives a proof of existence of natural frequencies for systems with artificial restraints (springs) having positive or negative stiffness coefficients, and their convergence towards constrained systems.
According to scholars who take the form of the Proslogion as meditation seriously, that form makes it impossible to understand the argument as a "proof" for God's existence designed to convince an agnostic or atheist on a purely rational level.
This conclusion was based on antibody testing by virus neutralization, a highly specific test that can discriminate serotypes within a single species, but formal proof for existence of serotypes was lacking.
Next, we present the proof for existence and uniqueness of a solution to DRWL in Theorems 3.1 and 3.2, for both (mathcal {R}_{j}, j in {1,2}) and (mathcal {B}), respectively.
