Indices

 

in number theory numbers that in the solution of congruences play a role similar to the role of logarithms in the solution of exponential equations. If p is an odd prime and g is a primitive root with respect to the modulus p, then the index of number a is a number k = ind a such that a = gk(mod p). The properties of indices are

ind ab = ind a + ind b (mod p— 1)

ind (a/b) = ind a— ind b (mod p - 1)

where a/b should be construed as the solution of the congruence bx ≡ a(mod p). Indices can be used to convert a congruence of the form axn ≡ b(mod p) to a linear congruence ind a + n ind x≡ ind b(mod p— 1). Because of the practical use of indices, there are special tables for every prime modulus p (that is not too large). In 1839 the German mathematician C. Jacobi compiled a table of indices for all prime numbers to 1,000. The Soviet mathematician. I. M. Vinogradov has done important studies on the distribution of indices.

Patient discussion about indices

Q. What could be the reason? I do go for exercise but the result is not satisfactory to me although I followed good diet, timing etc. What could be the reason?A. can you list in detail here what you do, what you eat? etc? Your successes and failures? Then we can help you a bit more. Maybe you have plateaued and need to change things up.

Q. What the reasons to the migraine? A. A migraine headache has many triggers- among which are different foods (cheese, red wine), drinking coffee or caffeine containing beverages, lack of sleep, smoking, drinking alcohol, exposure to strong noise and more. There is also a genetic factor, and you see migraine more in people whose relatives suffer from it too.

Q. what do you think the reason would be? As per the latest statistics that 2 out of 150 kids born in the U.S. has autism, and the incidence rate is increasing, what do you think the reason would be?A. The actual statistics is not 2 out of 150. It is 1 out of 150. I don't think autism is increasing, I think more children are being labeled as autistic - the condition is more well known than it was 20 years ago.
