similar tothe signs used in math. In this way, a propositioncan be presented in a logical form, and analyzedaccording to the rules of logic, so that the argument canbe tested in a similar way to a mathematicalproof. ++Gottlob Fregewas a pioneer of logic, but his work received little ...
How to tell if a statement is valid or invalid in discrete math? Write the negation of the given statement. All squares are rectangles What is a mathematical phrase? What does FOIL stand for in Math? What is the relation between mathematical logic and set theory?
PROPOSITION (Logic)MODAL logicMATHEMATICAL logicThis article is a review of the book "Logical Consequence" by Gila Sher. The book provides an overview of the theory of logical consequence, focusing on the semantic definition of logical consequence. It discusses Tarski's approach to logical ...
In this paper we revisit an open problem posed by Aldous on the max-entropy win-probability martingale: given two players of equal strength, such that the win-probability is a martingale diffusion, which of these processes has maximum entropy and hence gives the most excitement for the spectators?
Hamilton’s quaternion number system is a non-commutative extension of the complex numbers, consisting of numbers of the form where are real numbers, and are anti-commuting square roots of with , , . While they are non-commutative, they do keep many other properties of the complex numbers: ...
All mathematical definitions are dictionary definitions. Without special notification, "definition" will be used in the place of "dictionary definition" in the following context. Theoretically, it is unnecessary ever to give a definition ... the definitions are no part of our subject, but are, ...
Definition : an explanation of the mathematical meaning of a word. Theorem :A statement that has been proven to be true. Is a theorem always true? A theorem is a statement having a proof in such a system. Once we have adopted a given proof system that is sound, and theaxioms are all...

is, compared to a “null hypothesis” . The mathematical formula here is Thus, provided one has (i) A precise formulation of the null hypothesis and the alternative hypothesis , and the new information ; (ii) A reasonable estimate of the prior odds ...
Huxley urged us, “Do not pretend that conclusions are certain which are not demonstrated or demonstrable.” He also said, “It is wrong for a man to say he is certain of the objective truth of a proposition unless he can provide evidence which logically justifies that certainty.” ...
