 Feb21 comment What is closed-form expression for $F(n)$ when $F(n)=F(n-1)+F(n-2)$ and $F(0)=a$,$F(1)=b$ and $a,b>0$? great, I have value of $F(n)$ and have to find smallest $a,b>0$ your answer is going to be very helpful Feb21 accepted What is closed-form expression for $F(n)$ when $F(n)=F(n-1)+F(n-2)$ and $F(0)=a$,$F(1)=b$ and $a,b>0$?

Jan23 comment Find $C$, if $A=CBC$, where $A$,$B$,$C$ are symmetric matrices. and could You tell me what would be the most intuitive assumption needed for obtaining unique solution if assumption "B is positive definite matrix" deosn't hold anymore ? Jan23 comment Find $C$, if $A=CBC$, where $A$,$B$,$C$ are symmetric matrices. @Rahul Narain I've edited my question Jan23 accepted Find $C$, if $A=CBC$, where $A$,$B$,$C$ are symmetric matrices.
