Euler-type Recurrence Relation for Arbitrary Arithmetical Function

A. David christopher

An interplay between the Lambert series and Euler's Pentagonal Number Theorem gives an Euler-type recurrence relation for any given arithmetical function. As consequences of this,…

Congruences Relating Regular Partition Functions, a Genearalised Tau Function and Partition Function Weighted Composition Sums

S. Sriram, A. David Christopher

Let $n$ and $t$ be positive integers with $t \geq 2$ . Let $R_{t} (n)$ be the number of $t$ -regular partitions of $n$ . A class of functions, denoted $τ_{k} (n)$ , is defined as follows: \[q…

The Number of Parts in the (Distinct) Partitions With Parts From a Set

A. David Christopher

The number of parts in the partitions (resp. distinct partitions) of $n$ with parts from a set were considered. Its generating functions were obtained. Consequently, we derive seve…
