Tenth Workshop on Intersection Types and Related Systems

6 March 2020, Turin

Affiliated with Types 2020

Web: http://www.di.unito.it/~deligu/ITRS2020/



Aims and Scope


Intersection types were introduced near the end of the 1970s to overcome 
the limitations of Curry's type assignment system and to provide a 
characterization of the strongly normalizing terms of the Lambda 
Calculus. The key idea is to introduce an intersection type constructor 
∧ such that a term of type t ∧ s can be used at both type t and s within 
the same context. This provides a finite polymorphism where various, 
even unrelated, types of the term are listed explicitly, differently 
from the more widely used universally quantified types where the 
polymorphic type is the common schema which stands for its various type 
instances. As a consequence, more terms (all and only the normalizing 
terms) can be typed than with universal polymorphism.


Although intersection types were initially intended for use in analyzing 
and/or synthesizing lambda models as well as in analyzing normalization 
properties, over the last twenty years the scope of the research on 
intersection types and related systems has broadened in many directions. 
Restricted (and more manageable) forms have been investigated, such as 
refinement types. Type systems based on intersection type theory have 
been extensively studied for practical purposes, such as program 
analysis and higher-order model checking. The dual notion of union types 
turned out to be quite useful for programming languages. Finally, the 
behavioural approach to types, which can give a static specification of 
computational properties, has become central in the most recent research 
on type theory.


The ITRS 2020 workshop aims to bring together researchers working on 
both the theory and practical applications of systems based on 
intersection types and related approaches. Possible topics for submitted 
papers include, but are not limited to:


  *

    Formal properties of systems with intersection types.

  *

    Results for related systems, such as union types, refinement types,
    or singleton types.

  *

    Applications to lambda calculus, pi-calculus and similar systems.

  *

    Applications for programming languages, program analysis, and
    program verification.

  *

    Applications for other areas, such as database query languages and
    program extraction from proofs.

  *

    Related approaches using behavioural/intensional types and/or
    denotational semantics to characterize computational properties.

  *

    Quantitative refinements of intersection types.


ITRS workshops have been held every two years; Information about the 
previous events is available at the ITRS home page.


Invited Speaker:

* Jeremy Siek  (Indiana University Bloomington)


Contributed talks:

Authors are invited to submit an abstract (2 pages bibliography 
excluded) in PDF format, through EasyChair. Publishing of a full paper 
is planned in post-proceedings to appear in EPTCS, therefore we 
recommend using the EPTCS macro package to prepare submissions. Informal 
proceedings will be made available at the workshop.


Program committee:

* Ugo de' Liguoro (Turin University)
