Enumeration of direct animals with lattice paths
Daniel Yaqubi (Ferdowsi University of Mashhad, Iran)
25 June 2021 (7 pm IST)
Abstract: The aim of this talk is the enumeration of direct animals with lattice paths. Lattice paths have been studied for a very long time, explicitly at least since the second half of the 19th century. A typical problem in lattice paths is the enumeration of all $\mathcal{S}$-lattice paths (lattice paths with respect to the set $\mathcal{S}$). A non-trivial simple case is the problem of finding the number of lattice paths starting from the origin $(0,0)$ and ending at a point $(m,n)$ using only right step $(1,0)$ and up step $(0,1)$ (i.e., $\mathcal{S}={(1,0),(0,1)}$).

FAQs
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.
