Some figures from my papers
_____________________________

From: Integer continued fractions for complex numbers, (2025) arXiv

The new continued fractions in this paper give each region in the Figure a unique address.


From: Topographs for binary quadratic forms and class numbers, Mathematika 71 (2025), pdf

How methods of reducing quadratic forms look on Conway's topographs.
      


From: Symmetric functions and a natural framework for combinatorial and number theoretic sequences, Res. Number Theory 9 (2023), pdf

These new harmonic multiset numbers include both kinds of Stirling numbers as special cases.



From: Stirling's approximation and a hidden link between two of Ramanujan's approximations, J. Combin. Theory Ser A197 (2023), pdf

These modified second-order Eulerian numbers satisfy the same recurrence but with different initial conditions. They are used to describe in detail two asymptotic expansions of Ramanujan.
   



From: Ramanujan's approximation to the exponential function and generalizations, Ramanujan J. 62 (2023), pdf

A generalization of some asymptotic results of Ramanujan, Buckholtz and Knuth requires the Szego curve in the Figure.



From: A generalization of the Riemann-Siegel formula, Math. Z. 303 (2023), pdf

This work gives precise asymptotics for the Riemann zeta function in the critical strip. The zeros of the polynomials needed in the main formula also seem to line up.
   

 

From: Rademacher's conjecture and expansions at roots of unity of products generating restricted partitions, J. Number Theory 216 (2020), pdf

The first Sylvester wave is initially a good approximation to the partition function, but then goes its own way.



From: A vertex and edge deletion game on graphs, Integers 18 (2018), pdf

Play this game on a graph: on your turn remove an edge or remove a vertex with all its incident edges. Take the last vertex to win. The nim-value 0 moves shown are winning.
   

 

From: Formulas for non-holomorphic Eisenstein series and for the Riemann zeta function at odd integers, Res. Number Theory 4 (2018), pdf

This lattice of Eisenstein series naturally breaks into the four parts shown.
 
 

From: Zeros of the dilogarithm, Math. Comp. 85 (2016), pdf 

The zeros of some polylogarithms form spirals.
   



From: Parabolic, Hyperbolic and Elliptic Poincare Series, with O. Imamoglu, Acta Arithmetica 139, (2009), pdf

How this scaling map works in the upper half plane.
