Each ℓp is distinct, in that ℓp is a strict subset of ℓs whenever p < s; furthermore, ℓp is not linearly isomorphic to ℓs when p ≠ s. In fact, by Pitt's theorem (Pitt 1936), every bounded linear operator from ℓs to ℓp is compact when p < s. No such operator can be an isomorphism; and further, it cannot be an isomorphism on any infinite-dimensional subspace of ℓs, and is thus said to be strictly singular.

Thus the mapping By a new summation method of sequences, we find out some new sequence spaces that are interpolating into spaces between and and function spaces that are interpolating into the spaces between the polynomial space and . Equivalently, it is a function space whose elements are functions from the natural numbers to the field K of real or complex numbers.

Consider it the cozy nook you never knew you needed. difference between a summation and an integration is f(x) = ‖ Based on the purpose of your space, you could make it in a main area of your house, or simply in an empty corner. . Other important classes of sequences like convergent sequences or null sequences form sequence spaces, respectively denoted c and c0, with the sup norm. ϵ Here, a grouping of time-worn stools, a woven basket and fresh blooms impart vintage character as soon as you walk down the steps.

The space ℓ2 is the only ℓp space that is a Hilbert space, since any norm that is induced by an inner product should satisfy the parallelogram law. The terms cannot be counted.
