Epsilon calculus

LOGICAL CALCULUS WITH A PRIMITIVE SYMBOL THAT DENOTES AN ARBITRARY VALUE SATISFYING A GIVEN PREDICATE OR, IF NO SUCH VALUE EXISTS, ANOTHER ARBITRARY VALUE

Epsilon operator; Epsilon substitution method; Epsilon terms

Hilbert's epsilon calculus is an extension of a formal language by the epsilon operator, where the epsilon operator substitutes for quantifiers in that language as a method leading to a proof of consistency for the extended formal language. The epsilon operator and epsilon substitution method are typically applied to a first-order predicate calculus, followed by a showing of consistency.

Graduate Women in Science

ORGANIZATION

Sigma Delta Epsilon; ΣΔΕ

Graduate Women in Science (GWIS), formerly known as Sigma Delta Epsilon Graduate Women in Science (SDE-GWIS), is an international organization for women in science, first established in 1921 at Cornell University in Ithaca, New York, United States. The organization currently has over 1,000 members and dozens of chapters spread across the United States as well as an international chapter that was established in 2013.

Limit of a function

In mathematics, the limit of a function is a fundamental concept in calculus and analysis concerning the behavior of that function near a particular input.

Formal definitions, first devised in the early 19th century, are given below. Informally, a function f assigns an output f(x) to every input x. We say that the function has a limit L at an input p, if f(x) gets closer and closer to L as x moves closer and closer to p. More specifically, when f is applied to any input sufficiently close to p, the output value is forced arbitrarily close to L. On the other hand, if some inputs very close to p are taken to outputs that stay a fixed distance apart, then we say the limit does not exist.

The notion of a limit has many applications in modern calculus. In particular, the many definitions of continuity employ the concept of limit: roughly, a function is continuous if all of its limits agree with the values of the function. The concept of limit also appears in the definition of the derivative: in the calculus of one variable, this is the limiting value of the slope of secant lines to the graph of a function.
