Chapter 3.1, Problem 3E
Interpretation Introduction

Interpretation:

To sketch all the qualitatively different vector fields for x˙ = r + x - ln(1+x) that occur as r varies, and a saddle-node bifurcation point which occurs ata critical value of r is to be determined. Also, the bifurcation diagram of fixed points x*vs r is to be sketched.

Concept Introduction:

The qualitative change in the dynamics of the flow with parameters is called bifurcation and the points at which this occurs is called bifurcation point.

Bifurcation is used to study the stability of the dynamical systems.

Saddle-node bifurcation is one of the bifurcation mechanism in which fixed points create, collide and destroy.

Design a PDA recognizing each of the following languages and draw its state diagram. Note that the transition function must be in the format of “a, b →c", namely we can only push/pop one symbol into/from the stack one time upon one input symbol. You will receive 0 point if you push/pop multiple symbols into/from the stack one time upon one input symbol. (1) {w|wa"b", n is odd} = (2) {w|w=w², length of w is odd and Σ = {a,b} } (3) {w|w= = a²b²n, n ≥1 } (4) {w|w= =a^bn+mcm, n≥0, m ≥ 1 } (5) {w|w=a²b³n, n≥0} (6) {w|w= = a¹³, n ≥ 1, m≥ 1 and n‡m } Hint: two cases: n > m and n
