Uppercase Ε, lowercase ε or lunate ϵ; Greek: έψιλον) is the 5th letter of the Greek alphabet, corresponding phonetically to a close-mid front unrounded vowel /e/. In the system of Greek numerals it has the value 5.. It was derived from the Phoenician letter He He...Ho Ho Letters that arose from epsilon include the Roman E and Cyrillic Е..The LunateEpsilon (ϵ) is not to be confused with the set membership symbol (∈); nor should the Latin uppercase epsilon (Ɛ) be confused with the Greek uppercase sigma (Σ)..Epilepsy (from the Ancient Greek verb ἐπιλαμβάνειν meaning "to seize, possess, or afflict") is a group of long-term neurological disorders characterized by epileptic seizures..The term scalar matrix is used to denote a matrix of the form kI where k is a scalar and I is the identity matrix...

 The Heaviside step function, or the unit step function, usually denoted by H (but sometimes u or θ), is a discontinuous function whose value is zero for negative argument and one for positive argument. It seldom matters what value is used for H(0), since H is mostly used as a distribution..In mathematics, the Lp spaces are function spaces defined using a natural generalization of the p-norm for finite-dimensional vector spaces..A vector space is a mathematical structure formed by a collection of elements called vectors, which may be added together and multiplied ("scaled") by numbers, called scalars in this context..Vectors in vector spaces do not necessarily have to be arrow-like objects as they appear in the mentioned examples: Vectors are best thought of as abstract mathematical objects with particular properties, which in some cases can be visualized as Arrows.. Furthermore, vector spaces furnish aN abstract, coordinate-free way of dealing with geometrical and physical objects such as tensors. This in turn allows the examination of local properties of MANIfolds by linearization techniques.. Vector spaces may be generalized in several ways, leading to more advanced notions in geometry and abstract algebra...In linear algebra, real numbers are called scalars and relate to vectors in a vector space through the operation of scalar multiplication, in which a vector can be multiplied by a number to produce another vector..More generally, a vector space may be defined by using any field instead of real numbers, such as complex numbers. Then the scalars of that vector space will be the elements of the Associated Field...
