### A Logic of Sequentiality [chapter]

Martin Churchill, James Laird
2010 Lecture Notes in Computer Science
In this paper, we develop a detailed analysis of the structure of these strategies from a logical perspective by showing that they correspond to proofs in a new kind of affine logic.  ...  We describe the semantics of our logic formally by giving a notion of categorical model and an instance based on a simple category of games.  ...  Our work attempts to give a logical description of such strategies.  ...

### On the Unity of Logic: a Sequential, Unpolarized Approach [article]

2019 arXiv   pre-print
The present work aims to give a unity of logic via standard sequential, unpolarized games.  ...  In search for the truly linear refinement of CL, we carve out (a sequent calculus of) linear logic negative (LL^-) from (the two-sided sequent calculus of) LL, and introducing a new distribution axiom  ...  of IL into ILL, giving a sequential, unpolarized unity of logic (n.b., classicalization is the inverse of intuitionistic restriction).  ...

### A Deontic Action Logic with Sequential Composition of Actions [chapter]

Piotr Kulicki, Robert Trypuz
2012 Lecture Notes in Computer Science
Then we discuss the validity of formulas constructed in a language with a finite number of basic actions, parallel and sequential compositions of actions, a free choice operator and the standard deontic  ...  The main achievements of the paper are definitions of metalogical counterparts of deontic operators and interpretation function of actions taking into account their terminating and non-terminating executions  ...  In the present paper we want to extend the semantics of our systems on transitions between situations and extend the language of our deontic action logic with sequential composition of actions.  ...

### A Purely Logical Account of Sequentiality in Proof Search [chapter]

Paola Bruscoli
2002 Lecture Notes in Computer Science
The process algebra is a minimal restriction of CCS to parallel and sequential composition; the logical system is a minimal extension of multiplicative linear logic.  ...  This way we get the first purely logical account of sequentiality in proof search.  ...  This non-commutative operator, called seq, has a resemblance to the prefix combinator of CCS  ; it is a form of sequential composition, similar to other sequential constructs in other languages.  ...

### Design of a Ternary Edge-Triggered D Flip-Flap-Flop for Multiple-Valued Sequential Logic [article]

Reza Faghih Mirzaee, Niloofar Farahani
2017 arXiv   pre-print
The basic element of sequential logic is Flip-Flop, which stores an input value and returns two outputs (Q and Q_bar).  ...  Development of large computerized systems requires both combinational and sequential circuits.  ...  The Proposed Design The basic memory core in sequential logic is called latch. The well-known R-S latch is a pair of cross-coupled NOR gates.  ...

### Nondeterministic testing of Sequential Quantum Logic propositions on a quantum computer [article]

M. S. Leifer
2005 arXiv   pre-print
Such a Sequential Quantum Logic (SQL) was developed in the late 70's and has more recently been applied to the consistent histories framework of quantum mechanics as a possible route to the theory of quantum  ...  This suggests that the underlying logic of quantum computing may be an algebra of sequences of quantum measurements rather than an algebra of products of unitary operators.  ...  Acknowledgments: I would like to thank Howard Barnum and Elham Kashefi for useful discussions and Rob Spekkens for comments on an earlier version of this manuscript.  ...

### Designing sequential transcription logic: a simple genetic circuit for conditional memory

Georg Fritz, Nicolas E. Buchler, Terence Hwa, Ulrich Gerland
2007 Journal of Systems and Synthetic Biology
However, our results suggest that such sequential logic elements may be readily implemented by cells through the combination of existing protein-protein interactions and simple transcriptional regulation  ...  Here, we propose a simple genetic circuit in bacteria that is capable of conditionally memorizing a signal in the form of a transcription factor concentration.  ...  Timmer (University of Freiburg) for guidance and support during his diploma thesis.

### Growing Commas. A Study of Sequentiality and Concatenation

Albert Visser
2009 Notre Dame Journal of Formal Logic
We determine a reasonable extension of TC that is sequential, i.e., has a good sequence coding. C A Model without a Tally 23 2  ...  In his paper [Grz05], Andrzej Grzegorczyk introduces a theory of concatenation TC. We show that TC does not define pairing.  ...  We borrow some ideas from the proof of Lemma 6.5 of a forthcoming paper by Harvey Friedman, called The Inevitability of Logical Strength: Strict Reverse Mathematics.  ...

### A Constant-Space Sequential Model of Computation for First-Order Logic

Steven Lindell
1998 Information and Computation
We define and justify a natural sequential model of computation with a constant amount of read write work space, despite unlimited (polynomial) access to read-only input and write-only output.  ...  We show that computation on this model is equivalent to expressibility in first-order logic, giving a duality between (read-once) constant-space serial algorithms and constant-time parallel algorithms.  ...  using tape heads instead of the random-access method I was using).  ...

### A sequential abstract machine for flat concurrent prolog

Avshalom Houri, Ehud Shapiro
1989 The Journal of Logic Programming
SEQUENTIAL ABSTRACT MACHINE FOR FCP 87 An FCP term is either a variable or a structure.  ...  where H is the head of the clause, each Gi is a system-defined test called a guard, and each B, is a general body goal. An FCP program is a finite set of clauses.  ...  The design of the abstract machine and the implementation of its emulator were part of a group project, and ideas of many are incorporated in this work.  ...
