• Will journals become obsolete with the future advances of the web?

• How long does it take to find out whether a paper is relevant for your research?


• Is the following reference OK: “N. Nakatani. On Fibonacci Numbers. Technical Report, 2004 “ ?

• Is the following citation OK: “For the resolution method, see [Miller, Mayr 2004]” ?

• [Miller, Mayr 2004], A. Miller, C. Mayr, “An introduction to the resolution method”, J of S …, pp. , 2004.

Bibliographic Data



Working with the Literature: Search


An “Algorithm” for Literature Search: Given: a “topic”. Find: all relevant literature on the topic.

cites BA

Form theSymmetric,transitiveclosure of

cites


• Research Index, see citeseer.ist.psu.edu/cs•"CompuMath Citation Index " (CMCI), see www.isinet.com/products/citation/specialty/cmci• search for math / CS search engines

• “forward search” is possible!

An “Algorithm” for Literature Search:

Given: a “topic”Find: all relevant literature on the topic.

Web•Search engines•Citation indices


• Authors are happy if you ask about their papers!

Ask colleagues.

Use available papers.

• Use reference lists for backward search.


• authors’ index• keyword (subject index)

• thesauri are a problem!• example: AMS Subject Classification Scheme.

• the documentation of math is not problem oriented!

Use libraries.


An experiment: search for “equations”:

• for linear equations (over fields), search under the keyword "linear algebra"

• for linear equations (over the integers), search under the keyword "number theory"

• for nonlinear equations (over fields), search under the keyword "algebraic geometry"

• for numerical methods for equations solving (in the real and complex numbers), search under the kewyord "numerical mathematics"

• for nonlinear equations over the integers, search under the kewyord "recursive function theory" ("algorithm theory, or even "metamathematics").

• for differential equations, search under the keyword "differential equations“.

• e.g. Mathematical Reviews

• e.g. Current Mathematical Publications

• bibliographies /= literature surveys

Consult review journals,contents journals,

bibliographies.


Iterate

• i.e. form the symmetric, transitive closure of the relation “A cites B” (i.e. iterate forward, backward search)

• and prune irrelevant items at each step

• until the literature set stabilizes.


• prune:

• by reading title and abstract

title and abstract are enormously important

• the decision not to read a paper is very important


Advice:

• Be embedded into the research community:

• local• national• regional• global




Bibliographic Data

Working with the Literature Searching Literature– Reading Papers– Documenting


Working with the Literature: Read

Two opposing aspects:

– analyze quickly the essential contents of a paper

– understand and check details.


An “Algorithm” for Fast Reading:

Given: a paper.Find: the relevant contents.

Read (in this order)

• title and abstract• reference list• conclusion• introduction and literature review

Please see the lecture notes

for details.


Clarify and formulate in your own words

• the essential problems treated• the new contribution to their solution

For each problem, proceed by “Gerber’s Rule”:

– What is given?– What has to be found?


• Look to concrete problem instances.

• What is given and what has to be found in the example?

• How would you solve the problem? What do you know about known solutions in the literature?

• What is specific about the problem, i.e. what distinguishes the problem from other, similar problems?

• What is the specific difficulty of the problem?

• How could the problem be specified formally?


• What might be the specific contribution of the paper to the solution of the problem (even if you did not yet see the details presented in the paper)?

• Is the problem and its solution relevant for your topic?


Is PaperRelevant for You?

no Exit.

yes


Understand and check the relevant details.

• Look up (in case you don’t know) the relevant terminology and results in the area.

• Get the intuitions behind the formal details.

• Checking the formal details.


• For (getting the intuitions and) checking the formal details:

• Complete mastery of the formal methodology of mathematics (“reasoning”) is necessary, see Course on “Mathematical Thinking”.

• This can be learned!




Bibliographic Data

Working with the Literature Searching Literature Reading Papers– Documenting


Working with the Literature: Document

• Complete documentation of the literature used in your paper is obligatory:

– For making the paper completely understandable.

– For giving intellectual credit to the results used.


Steps:

• documentation during work

• the reference list

• citing

• the literature review

• (bibliographies)


Documentation during work:

• a list of all references (ordered alphabetically by authors) with complete bibliographic data

• and keywords.


The reference list:

• completeness of bibliographic data

• uniformity.


Citing:

• Cite all papers which you use in your paper.• Cite the papers in which the results appeared for the first time

(“primary literature”).• Cite also papers in which the results are well presented

(“secondary literature”)• Cite sufficiently many papers for making your paper

understandable.• Do not include papers into the reference list which you did not

use in your paper.• Be careful with self-citations.• Think about “personal communications”.


Literature review:

• May go by authors. • Should be summarized in a “statement of originality”.

• In addition, individual citations in the text will often be necessary.

• Bibliographies are different: Are independent of one’s own paper, go by “topic” (preferably, by “problems”), see lecture notes.


Repetition: Points of Emphasis

• The Refereeing Procedure

• Efficient Search

• Efficient Reading

• Give Credit


Exercises

Check: Can you answer the initial questions?


Exercise:

• choose (a very limited) topic (advice: a “problem”; we might take the problem of your future master’s thesis);

• search the relevant literature using the “algorithm” above;

• read the papers found (to the point where you can determine the relevance and essential contributions of the papers)

• document the result of the literature search.
