Let L = {w! w can be written as cd#e#c with c, d, e e {a,b}* }. Show that is not regular.
4. (10) Let L = {w w can be written as cd#e#c with c, d, e e {a, b}* }. Show that L is not regular.
Let L be a regular language on sigma = {a, b, d, e}. Let L' be the set of strings in L that contain the substring aab. Show that L' is a regular language.
Let ?= (a, b). The Language L = {w E ?. : na(w) < na(w)) is not regular. (Note: na(w) and nu(w) are the number of a's and 's in tw, respectively.) To show this language is not regular, suppose you are given p. You now have complete choice of w. So choose wa+1, Of course you see how this satisfies the requirements of words in the language. Now, answer the following: (a) What is the largest value of lryl?...
Prove that the following language is not regular: L = { w | w ∈ {a,b,c,d,e}* and w = wr}. So L is a palindrome made up of the letters a, b, c, d, and e.
(d) Let L be any regular language. Use the Pumping Lemma to show that In > 1 such that for all w E L such that|> n, there is another string ve L such that lvl <n. (4 marks) (e) Let L be a regular language over {0,1}. Show how we can use the previous result to show that in order to determine whether or not L is empty, we need only test at most 2" – 1 strings.

(1) Let w1, be a k-form and w2 be an l- form, both defined in an open subset UC R3. Let d : /\k (U)-ל ЛК +1 (U) be the exterior derivative of differential forms. (a) Show that d is a linear transformation of vector spaces. (b) Show that (c) Show that (d) Show that d(w) -d(d(w)) 0 for every k-form w, i.e. the map is the zero map (1) Let w1, be a k-form and w2 be an l-...
Let S = {a, b}. Show that the language L = {w EX : na(w)<n(w) } is not regular.
Let W1 and W, be the subspaces of a vector space V. Show that WinW, is a subspace of V.
Problem 13.5. Let V and W be inner product spaces and T є L(V : W). Let(..) v and (..)w denote their respective mner products. Let ui, , uk be an orthonormal basts o V and W1,…,wn an orthonormal bass o W. Let A and A* be the matrices representing T and T with respect to the given bases. Show that A. = A i.e., A. is obtained from A by taking the transpose and conjugating all the entries (in...
