**When does the seminar take place?**

Usually on Fridays, the times change depending on the availability of the speaker.

**Who can attend?**

Everyone is welcome to attend. You can register to be on the mailing list by filling in this form.

**Who can give a talk?**

At the moment we are encouraging only PhD students, postdocs and young faculty members to give talks. If you are interested in giving a talk, please send an email to [email protected] or [email protected]

**Are the talks meant for a general audience?**

Yes, but this is a research seminar. We ask the speakers to spend at least 30% of their time on introduction and motivation of the topic which should be understandable for someone with a Masters level education in mathematics.

**How long is a talk?**

The talks are between 45-60 minutes, followed by discussions. We leave the discussions open ended and usually spend about 60 minutes after the talk just chatting with each other about various topics related to mathematics.

**Why was this series started?**

The primary aim was to know the different type of work being done by young mathematicians and to also look for oppurtunities for collaborative work.

**Will there be any certificate for attending?**

No.

**Are there recordings of the talks?**

No. Only the speaker has access to recordings of their own talks. The speakers can decide to make them public if they wish to.
