22-6

UU: Talk by Paul Hovland (Argonne National Laboratories, USA) on:

Some combinatorial problems in derivative computation

15.30-16.30 hr in HFG 611, Budapestlaan 6, De Uithof, Utrecht
Abstract:

We discuss some combinatorial problems arising in the efficientcomputation of derivatives. In one problem, given a directed acyclic graph (DAG) representation of a function, we seek to transform the DAG into an equivalent bipartite graph at minimal cost. In a related problem, we seek to transform the DAG into an equivalent DAG with the smallest possible number of edges.  We describe heuristics and integer programming formulations for both problems.

In both discrete and continuous adjoint methods for derivative computation, one must often trade recomputation for storage.

We discuss some combinatorial problems arising from this tradeoff, focusing on the case where intermediate state might be written to both memory and disk.

Young Researchers in Mathematics Conference 2015 (YRM2015)
Date/location:? August 17th-20th, 2015, Andrew Wiles Building- Mathematical Inst. Univ. Oxford, Oxford

The YRM2015 conference is primarily intended for PhD students in Mathematics and related disciplines (Statistics, Computer Science, Physics, etc.). Other early-career researchers are also very welcome (e.g. Master students with some research experience, Post-Docs, etc.).
There will be talks by young researchers, plenary and keynote talks by dis?tinguished speakers across Mathematics, a poster competition, and a Quanti?tative Finance workshop from G-research.

All participants are invited to give a short (15 minutes + 5 minutes for questions) talk on their research. These talks will be organised into tracks which reflect different fields of research.

ECC 2015 Elliptic Curve Cryptography 2015 (ECC 2015)
Dates: Summer school:
September 23-25
Workshop:
September 28-30

 

Website, email

EARLY BIRD PREREGISTRATION ENDS THIS WEEK!

ECC 2015 is the 19th in a series of annual workshops dedicated to the study of elliptic curve cryptography and related areas. Over the past years the ECC conference series has broadened its scope beyond elliptic curve cryptography and now covers a wide range of areas within modern cryptography.

For instance, past ECC conferences included presentations on hyperelliptic curve cryptography, pairing-based cryptography, side-channel attacks, voting protocols, quantum key distribution, AES, hash functions and implementation issues. At the same time ECC continues to be the premier conference on elliptic curve cryptography. It is hoped that ECC 2015 will further our mission of encouraging and stimulating research on the security and implementation of elliptic curve cryptosystems and related areas, and that it will encourage collaboration between mathematicians, computer scientists and engineers in the academic, industry and government sectors.

There will be about fifteen invited lectures (and no contributed talks) delivered by internationally leading experts, giving both state-of-the-art

survey lectures as well as presentations of latest research developments.

This year, there will also be a panel discussion on standardisation of elliptic curves for cryptography.

There will be a rump session at the conference on Monday evening, where participants can give short and entertaining presentations of recent results, work in progress, or make announcements of interest to attendees.

A call for submissions for the rump session will be issued to registrants before the event.

The following invited speakers have already confirmed their participation:

L?o Ducas (CWI, Netherlands): Recovering Short Generators of Principal Ideals in Cyclotomic Rings; Steven Galbraith (University of Auckland, New Zealand): Algorithms for the ECDLP, Christian Grothoff (INRIA Rennes-Bretagne-Atlantique, France): Cryptography in GNUnet: Protocols for a Future Internet for Libre Societies; Aurore Guillevic (?cole polytechnique and INRIA Saclay-?le-de-France, France): Computing discrete logarithms faster in F_{p^n} with the Number Field Sieve algorithm;

Michael Hamburg (Cryptography Research, USA), Michiel Kosters (Nanyang Tech?nological University, Singapore), Juliane Kr?mer (Technische Universit?t Darmstadt, Germany), Enea Milio (INRIA Bordeaux-Sud-Ouest, France):

Computation of modular polynomials in dimension 2;

C?cile Pierrot (CNRS, DGA and Sorbonne Universit?s, UPMC, France):

Discrete Logarithms in Medium Characteristic Finite Fields;

Peter Schwabe (Radboud University, Netherlands):

Verifying ECC software;

Katherine Stange (University of Colorado, USA), Arnaud Tisserand (CNRS, Universit? de Rennes and INRIA-Bretagne-Atlantique, France).

Abstracts are available on the conference web site.

 

The conference is preceded by a summerschool on elliptic curve cryptology and related areas of interest for the conference. Courses are intended for

students preparing a master or doctoral degree.

 

Preregistration is now open at the conference web site. There are no registration fees for the summer school or the conference, but we have to limit the number of participants; so we will contact you after

the preregistration to confirm whether your application has been accepted, and will ask you for a final confirmation of your participation.

 

Early bird preregistration: June 19

Early bird notification:    June 22

Late preregistration:       August 12 (within the limits of available places)

Late notification:          August 14

I wanted to draw your attention to /*several current openings for senior faculty positions (associate professor/full professor) in applied mathematics*/ in the School:
http://jobs.monash.edu.au/jobDetails.asp?sJobIDs=534771

Outstanding candidates are sought in all areas of applied mathematics;

*/numerical analysis and scientific computing are listed among the areas of specific interest/*

(this includes numerical PDEs, numerical linear algebra, numerical optimization, computational finance, computational statistics, uncertainty quantification, data science, etc.).

Monash is a leading Australian research university that is globally ranked in the top 100, and Melbourne is recognized as being a great place to live.

/*If you know of someone who may be interested, please forward them this message and the link above.*/

Applications close Thursday 2 July 2015 (with apologies for the late notice?).

It is expected that several additional openings at more junior levels(Lecturer/Senior Lecturer, continuing appointments) will be advertised later this summer.
