Publications 1971-80

Here is an annotated list of publications.

M. Hyland. A syntactic characterisation of the Equality in some Models of the Lambda Calculus.
Journal of the London Mathematical Society, 12, 1976, 361-370.
This characterises equalities in the standard Scott model and in the P-omega for the lambda calculus.

J. M. E. Hyland. A survey of some useful partial order relations on terms of the Lambda Calculus.
In C. Bohm (editor), Lambda Calculus and Computer Science Theory, Springer Lecture Notes in Computer Science 37, 1976, 83-93.
I shall get round to explaining some corrections and possible misunderstandings soon.

R. O. Gandy and J. M. E. Hyland. Computable and recursively countable functionals of higher type.
In R. O. Gandy and J. M. E. Hyland (editors), Logic Colloquium 76, North-Holland, 1977, 407-438.
This joint paper with my D.Phil supervisor Robin Gandy contains recursion-theoretic material some chosen from my thesis and some previously unpublished work of Gandy.

J. M. E. Hyland. Aspects of constructivity.
In R. O. Gandy and J. M. E. Hyland (editors), Logic Colloquium 76, North-Holland, 1977, 407-438.
This is based on my talk at Logic Colloquium 1976 in Oxford. It combines ideas about sheaf models with techniques from Troelstra. The perspective is crude and when Mike Fourman discovered his model for choices sequences it was clear that the material should be reformulated using that. But I have never got round to doing so.

J. M. E. Hyland. The intrinsic recursion theory on the countable or continuous functionals.
In J. E. Fenstad, R. O. Gandy and G. E. Sacks (editors), Generalized Recursion Theory II, North-Holland, 1978, 135-145.

J. M. E. Hyland. Filter spaces and continuous functionals.
Annals of Mathematical Logic 16, 1979, 101-143.
This paper contains much of the abstract work in my DPhil thesis.

M. P. Fourman and J. M. E. Hyland. Sheaf models for analysis.
In M. P. Fourman, C. J. Mulvey and D. S. Scott (editors), Applications of Sheaves, Springer Lecture Notes in Mathematics 753, 1979, 280-301.

J. M. E. Hyland. Continuity in Spatial Toposes.
In M. P. Fourman, C. J. Mulvey and D. S. Scott (editors), Applications of Sheaves, Springer Lecture Notes in Mathematics 753, 1979, 442-465.

J. M. E. Hyland, P. T. Johnstone and A. M. Pitts. Tripos Theory.
Mathematical Proceedings of the Cambridge Philosophical Society, 88, 1980, 205-232.
