    Convergent Series Sum

SUMMARY

The sum of the convergent series S = t^(-1) + t^(-4) + t^(-9) + ... for n=1 to ∞, where t > 1, is expressed as S = [θ3(1/t) - 1]/2, with θ3 representing the Jacobi theta function. The series converges as confirmed by the ratio test. There is a strong suspicion that S is transcendental for integer values of t, although concrete references and arguments are lacking in the discussion.

PREREQUISITES
  • Understanding of convergent series and the ratio test
  • Familiarity with Jacobi theta functions
  • Basic knowledge of transcendental numbers
  • Experience in mathematical analysis
NEXT STEPS
  • Research Jacobi theta functions and their properties
  • Explore the concept of transcendental numbers and their implications
  • Study advanced techniques in series convergence
  • Investigate mathematical proofs related to the sum of series
USEFUL FOR

Mathematics students, educators, and researchers interested in series convergence, special functions, and transcendental number theory.

what is the sum of the following series? I know it's convergent (using ratio test) but I'm not able to work it out :(
S=t^(-1) + t^(-4)+t^(-9)...t^(k^2)...to ∞
where t>1
Thanks

S = [θ3(1/t)-1]/2, where θ3 is a Jacobi theta function. I strongly suspect S is transcendental for integer t, but couldn't easily find a good reference, nor a convincing argument.
 
Hey everyone
Im a maths tutor and this question was given to one of my students. i may be thinking about it to cryptically so i thought id post it

5,9,13 ,27,,,217

i have posted it to various other pupils but no one has gotten it yet.
