Regular languages are closed under complement, union, intersection, concatenation, Kleene star, reversal, homomorphism, and substitution.
Closure properties on regular languages are defined as certain operations on regular language that are guaranteed to produce regular language. Closure refers to some operation on a language, resulting in a new language that is of the same “type” as originally operated on i.e., regular.

In class, we proved that the set of regular languages is closed under union. The idea behind the proof was that, given two DFAs D1,D2, we could make a new DFA D3 which simultaneously keeps track of which state we're at in each DFA when processing a string.
The closure properties of a regular language include union, concatenation, intersection, Kleene, complement , reverse and many more operations.
Closure property states that any operation conducted on elements within a set gives a result which is within the same set of elements. Integers are either positive, negative or zero. They are whole and not fractional. Integers are closed under addition.
Regular languages are closed under union, concatenation, star, and complementation.
Regular Languages are closed under intersection, i.e., if L1 and L2 are regular then L1 ∩ L2 is also regular. L1 and L2 are regular • L1 ∪ L2 is regular • Hence, L1 ∩ L2 = L1 ∪ L2 is regular.
