Control and Automation Engineer Main Mathematical Interests: Integration, Infinite Series and Elementary Number Theory. One particular interest is finding new Infinite Series for Apéry`s Constant and other Zeta Constants e.g. this especially strange one I found for Apéry`s Constant last year (2016), $$zeta(3)=$$ $$frac{1}{2}frac{8}{7} left(frac{pi}{2}right)^3 left(frac{pi}{4}right)^3 left( b_{1} lvert B_{4}rvert + b_{2} lvert B_{6} rvert left(frac{pi}{4}right)^2 + b_{3} lvert B_{8} rvert left(frac{pi}{4}right)^4+ ; ... right)$$ where $ b_k=left( frac{2^{2k+2}left( 2^{2k+2}-1right)left( 2^{2k+1}-left( k+2right)right)}{left( 2k+2right)! ; left( k+1right)left( k+2right)} right)$ and where $lvert B_{2k+2}rvert =left(-1 right)^k ; B_{2k+2}$ are unsigned Bernoulli Numbers. Other simpler slowly converging series I have found for $lambda(3)$ are: $$lambda(3)=frac{pi^2}{4}sum_{k=1}^{infty} frac{beta(2k-1)}{(2k-1)(2k+1)}$$ and $$lambda(3)=frac{pi^2}{4}sum_{k=1}^{infty} frac{lambda(2k)}{(k+1)(2k+1)}$$ where $lambda(n)=sum_{k=1}^{infty} frac{1}{(2k-1)^n}$ and $beta(n)=sum_{k=1}^{infty} frac{(-1)^{k-1}}{(2k-1)^n}$ The analogous series for $lambda(5)$ are $$lambda(5)=frac{pi^4}{3times2^4}sum_{k=1}^{infty} frac{beta(2k-1)(2k+4)}{(2k-1)(2k+1)(2k+3)}$$ and $$lambda(5)=frac{pi^4}{4!}sum_{k=1}^{infty} frac{lambda(2k)(2k+7)}{(2k+1)(2k+3)(2k+4)}$$ Also interested in learning more about the relation between Maths and Physics. ©
