Spring 2012

All assignments are due in class on the date shown.  On the first page of homework assignments, write a list of any assigned problems that you did not finish (it should be a short list).  Show your work.  I strongly encourage you to work in groups, but you must write up the results yourself.

By 9:00 on the morning of the seminar date (if there is one), email me a listing of:
Assignments are from Devaney, except those marked GS, which are from Grinstead and Snell.

Date due Assignment
Fri 1/20 Math questionnaire
Fri 1/27 (seminar day Wed 1/25) Experiment 3.6 (p. 25), for the doubling function D only (the Maple worksheet iterateDoublingMap.mw may be helpful, or Excel, or this applet)
3 (p.26) #1, 3, 5-10, 13, 14
4 (p.34) #1, 5, 6, 7
Mon 2/6 (seminar day Fri 2/3) 5 (p.50) #1(a,c,j,k), 2(a,b,d), 3, 4(a,b), 5, 6

Let cn be the red blood cell count at time n.  If
cn+1 = (1 − a)cn + b(cn)r e^(−scn)  and
b=1,100,000, r=8, and s=16, show that there are two stable and one unstable fixed points when a=0.2.  How do you interpret this result in terms of the red blood cell count?
