Topological Spaces,ma and tiesze Extension Theorem that specifies that certain continuous functions exists for normal topological spaces. One key concept that we present is the notion of net. This is a generalized notion for sequences, and allows us to define integration for both Lebesgue and Riemann integrals.

Vector Spaces,echnical capabilities). We can define linear operators of vector space to vector space. The concept of linear combination, subspaces, product space, linear variety, linear independence, and dimension is introduced in vector spaces. For real or complex vector spaces (vector spaces over the field . or .), the concept of convexity can be defined.

Topological Spaces,bout closed sets, the closure of a set, the interior of a set, the boundary of a set, etc. The notions of limit and continuity of a function is intrinsically linked to topological spaces. We touch on the notions of basis of a topology, the countability of the topological space, the connectedness, th

Banach Spaces,a metric space structure, where the distance between two points is simply the length of the difference of the two points. Thus, we have all the tools for metric space and topological space at our disposal. A complete normed linear space is called a Banach space. For finite-dimensional Banach spaces,
