In mathematics|lang=en terms the difference between fiber and subbundle

is that fiber is (mathematics) the preimage of a given point in the range of a map while subbundle is (mathematics) a collection of linear subspaces of the fibers v_x'' of ''v'' at ''x'' in ''x'' (where ''v'' is a vector bundle and ''x a topological space), that make up a vector bundle in their own right.

As nouns the difference between fiber and subbundle

is that fiber is (countable) a single elongated piece of a given material, roughly round in cross-section, often twisted with other fibers to form thread while subbundle is (mathematics) a collection of linear subspaces of the fibers v_x'' of ''v'' at ''x'' in ''x'' (where ''v'' is a vector bundle and ''x a topological space), that make up a vector bundle in their own right.

As a noun subconvexity is

(mathematics) the state or condition of being subconvex.

As nouns the difference between sum and sumset

is that sum is noise (sound or signal generated by random fluctuations) while sumset is (mathematics) the set of all sums of an element from a'' with an element from ''b'', where ''a'' and ''b are subsets of an abelian group.

As nouns the difference between element and sumset

is that element is one of the simplest or essential parts or principles of which anything consists, or upon which the constitution or fundamental powers of anything are based while sumset is the set of all sums of an element from A with an element from B, where A and B are subsets of an abelian group.

As nouns the difference between subset and sumset

is that subset is with respect to another set, a set such that each of its elements is also an element of the other set while sumset is the set of all sums of an element from A with an element from B, where A and B are subsets of an abelian group.
