The Organising Committee respectfully offers the following suggestions for a successful presentation of your talk.

• At the 20^th conference of the International Linear Algebra Society, all talks are 25 minutes plus 5 minutes for questions.
• There is a projector in each room for your presentation. Laptops can be connected through VGA to the projector.
• All rooms are further equipped with an overhead projector and white- or blackboards, but in some rooms the blackboards cannot be used simultaneously with the projector! Larger rooms have a microphone. Please use it for your lecture.
• Please make sure that the font size on your slides is adequate for a large room. Any size larger than 24 pt should be adequate. Use only a landscape orientation.
• Audiences do not appreciate computer presentations that consist of images of pages of a paper, published or to be published. Never do this.
• The pages of your presentation should not be overcrowded with lines. If you have more than about 7 lines on a slide, it is probably too many and your font size is probably too small. Enlarge the font to fill the page, if necessary.
• Keep your presentation short. A good rule of thumb is: a bit less than one slide per minute of presentation, although this varies with each case. Practice your presentation to see how long it takes. If your first draft of you presentation has 50 slides for a 20-minute talk, it is way too many! You have time to include only the most important ideas and key points. Deciding what those ideas and points are, and organising them for your listeners, is your most important responsibility as a speaker.
• Avoid going back and forth on your slides. If it is necessary to show a slide again, put it twice in your PDF.
• Avoid both proofs and statements of long theorems with intricate hypotheses. Your audience expects you to share the big picture with them, not the details. They will be dismayed if you read them 20 theorems in a row!
• Avoid journal citations on your slides. If you wish your audience to know that a name is associated with some item on your slide, you can write something like [Jones 2001].
• Do not present long calculations. If it takes more than a line or two to illustrate how to work something out, omit it.
• If you use a laser pointer, use it only briefly from time to time to point to something that you wish the audience to focus on. Do not point at everything. Above all, do not keep waving the pointer around in circles during your presentation!
• Talk to your audience, not to the screen. Speak loudly enough to be heard at the back of the room. Speak slowly. Limiting the number and density of your slides will make it unnecessary to race through your presentation.
• Remember your own experiences as a member of the audience. Avoid doing the things that bother you when you listen to a talk.
• Above all, make your experience giving a talk a pleasant one.
