Some comments on Rota's Umbral Calculus
Rota's Umbral Calculus is put in the context of general Fourier analysis. Also, some shortcuts in the proofs are illustrated and a new characterization of sequences of binomial type is given.

Umbral calculus, binomial enumeration and chromatic polynomials
We develop the concept of partition categories, in order to extend the Mullin-Rota theory of binomial enumeration, and simultaneously to provide a natural setting for recent applications of the Roman-Rota umbral calculus to computations in algebraic ...

An introduction to Umbral Calculus
The aim of these lectures is to give an introduction to combinatorial aspects of Umbral Calculus. Seen in this light, Umbral Calculus is a theory of polynomials that count combinatorial objects.

A Regular Simply-Typed λ-Calculus
. What makes open terms different from closed terms is considered basic, intrinsic, natural, and obvious. This work revisits this age old concept and presents the regular simply-typed λ-calculus, a conservative extension of the simply typed λ-calculus ...

An Injective CPS-translation for the Extensional λ-calculus
We give a syntactical proof to the statement that a novel CPS translation with surjective pairing is injective for the extensional λ-calculus. The result itself might be preliminary, since the source language (the extensional λ-calculus) of the ...

Unification in a λ-calculus with intersection types
We propose related algorithms for unification and constraint simplification in λ → & , a refinement of the simply-typed λ-calculus with subtypes and bounded intersection types.

Modified Apostol-type polynomials arising from umbral calculus
In this paper, by using the orthogonality type as defined in the umbral calculus, we derive an explicit formula for several well-known polynomials as a linear combination of the modified Apostol-type ...

A note on poly-Bernoulli polynomials arising from umbral calculus
In this paper, we give some recurrence formula and new and interesting 732 Dae San Kim, Taekyun Kim and Sang-Hun Lee identities for the poly-Bernoulli numbers and polynomials which are derived from umbral ...

λ-calculus and types Lecture notes
1.1 A short history The λ-calculus was introduced by Alonzo Church in the 40ies. The initial goal was formalisation of mathematical reasoning, I believe.
