7) Define a set U of strings of a, b, and c recursively as follows: B. bEU R. If XEU, then axc EU. List four elements of U and apply structural induction to show that every element in U is in the form of a"bc", where n is a non-negative number
discrete math. Structural Induction: Please write and
explain clearly. Thank you.
Let S be the set of binary strings defined recursively as follows: Basis step: 0ES Recursive step: If r ES then 1rl E S and 0x0ES (I#x and y are binary strings then ry is the concatenation of and y. For instance, if 011 and y 101, then ry 011101.) (a) List the elements of S produced by te first 2 applications of the recursive definition. Find So, Si...
4. Suppose S is the set of numbers recursively defined by: lE S Use structural induction to prove that all members of S are integers of the form of 2a3 for some non-negative integers a, b.
QUESTION 10 The equality relationon any set S is: A total ordering and a function with an inverse. An equivalence relation and also function with an inverse. A function with an inverse, and an equivalence relation with as single equivalence class equal to S An equivalence relation and also a total ordering QUESTION 11 A binary operation on a set S, takes any two elements a,b E S and produces another element c e S. Examples of binary operations include...
(5) Fibonacci sequences in groups. The Fibonacci numbers F, are defined recursively by Fo = 0, Fi-1, and Fn Fn-1 + Fn-2 for n > 2. The definition of this sequence only depends on a binary operation. Since every group comes with a binary operation, we can define Fibonacc type sequences in any group. Let G be a group, and define the sequence (n in G as follows: Let ao, ai be elements of G, and define fo-ao fa and...
b) Let A-2,4 and B 1,3,5). Define the nonempty and pairwise different relations U, V, W C A x B as follows: . (x,y) E U implies 7 .(x,y) E V implies r > y . z > y implies (z, yje W. i. For wich of the above tasks would the empty set be a valid solution (if the "non- empty" wasn't given in the task)? ii. Determine if the relations U, V and W are functions and reason...
Please do exercise 129:
Exercise 128: Define r:N + N by r(n) = next(next(n)). Let f:N → N be the unique function that satisfies f(0) = 2 and f(next(n)) =r(f(n)) for all n E N. 102 1. Prove that f(3) = 8. 2. Prove that 2 <f(n) for all n E N. Exercise 129: Define r and f as in Exercise 128. Assume that x + y. Define r' = {(x,y),(y,x)}. Let g:N + {x,y} be the unique function that...
