It involves proper selection of f and g such that |g|<|f|
Trick : Always chose the f(z) to be a monomial from the given polynomial   terms.

interpolation on sobolev spaces

for 0<theta<1
 and a,b be positive numbers then
c=theta*a+(1-theta)*b

then a new sobolev space  S^c is given by  =[S^a ,S^b] for given theta such that  c=theta*a+(1-theta)*b

Madly fell in love with chess

The world championship between Anand and the kid, carlsen was the actual point that raised my Epinephrine(adrenalin) levels for the brutal mind game of chess. Previously I was an addict to stock market , now chess making me mad(playing all the nights on chess servers with worldwide players, of course losing all the matches). One more thing that doesn't need any explanation that i am an addict is Cricket(not TV watching). Still suffering from it . Next is, that  amazing math problems enticing me for all the day and night for a tireless romantic battle(won most of the times).
  Third is my fiance :)
