Solution of an algebraic equation 
  Hi, I would like to know how to solve: x^m -ax + a - 1 = 0 with a >1, m>1, a real and m integer. An obvious real solution, for each (a,m) satisfying the given constraints is x=1. I would like to find at least another real solution, for each (a,m), if it exists, or otherwise determine which additional constraints must be imposed on... more »

Topology with int, boundary. 
  Hello teacher~ T_1 : cofinite topology. T_2 : usual topology. A = [0, 1] x [0, 1] subset (R, T_1) x (R, T_2). int(A) = ? b(A) = ? ------------------------------ ---------------------- Since int(A) subset A, the projection pi_1[int(A)] is a subset of [0, 1] in (R, T_1) Since every subset(=/= empty) of [0,1] is not open in (R, T_1),... more »
