 >An Introduction to Configuration Spaces and Braid Groups</a>\nby Annalies
 e Keiser (University of Michigan) as part of Graduate Online Seminar Serie
 s (GOSS)\n\nLecture held in TBA.\n\nAbstract\nThis is an expository talk e
 xploring configuration spaces and braid groups. I will give definitions an
 d examples of configuration spaces and braid groups\, explore the connecti
 on between the two\, and\, time permitting\, state properties of each. I c
 onsider these ideas from the perspective of algebraic topology and combina
 torial group theory\, although these objects appear and have applications 
 in many other areas of mathematics.\n

 >The Math of ML Security</a>\nby Sven Cattell (Elastic) as part of Graduat
 e Online Seminar Series (GOSS)\n\nLecture held in TBA.\n\nAbstract\nSecuri
 ty is a cat and mouse game. Attackers innovate to bypass defenders\, and d
 efenders innovate to catch the new attacks. One of the promises of AI is i
 ts ability to adapt for us. However\, the machine learning models we deplo
 y are trained on a chronological snapshot of the ever-changing data. They 
 memorize and generalize well on that snapshot but are unreliable when the 
 landscape shifts\, or have various adversarial examples and other holes th
 at let attackers to bypass the ML models. This talk will focus on how this
  plays out mathematically on the large datasets we use to create these mod
 els. We will also talk about how I transitioned into this industrial space
 \, from a PhD in equivariant algebraic topology and advice that might make
  things easier for future grad students looking towards ML.\n\nBio: \nSven
  Cattell is a Senior Security Data Scientist at Elastic. He received his m
 athematics PhD from Johns Hopkins University where his thesis focused on e
 quivariant algebraic topology. During his post doctoral his focused shifte
 d to the geometry of machine learning. While working on his postdoc he co-
 founded the AI Village at DEFCON which will be at DEFCON for the fourth ti
 me this year. He also built a math exhibit for the National Science Fair i
 n DC and a game to teach kids about disinformation and spam. He now works 
 at Elastic Security on their malware models trying to improve the model an
 d secure it against adversarial attacks.\n

 >Heegaard Splittings and Trisections 101: A Crash Course in Manifold Decom
 positions in Dimensions Three and Four</a>\nby Nick Meyer (University of N
 ebraska\, Lincoln) as part of Graduate Online Seminar Series (GOSS)\n\nLec
 ture held in TBA.\n\nAbstract\nIn this talk\, I will discuss Heegaard spli
 ttings of 3-manifolds and trisections of 4-manifolds. These decompositions
  cut the manifold into 1-handlebodies of appropriate dimension whose commo
 n intersection is a closed\, orientable surface. By studying these decompo
 sitions\, we obtain lots of information about the manifolds that they dete
 rmine. This talk is based in part on David Gay's "From Heegaard splittings
  to trisections\; porting 3-dimensional ideas to dimension 4."\n

 >Stochastic Logistic Maps and Invariant Distributions</a>\nby Kimberly Aye
 rs (Cal State San Marcos) as part of Graduate Online Seminar Series (GOSS)
 \n\nLecture held in TBA.\n\nAbstract\nAbstract:  The logistic map\, given 
 by the mapping $f(x)=\\lambda x(1-x)$\, maps the interval $[0\,1]$ to itse
 lf when $\\lambda$ takes values between 0 and 4.  It's a famous example of
  a map that displays chaotic behavior - behavior that is seemingly without
  pattern or predictability.  One hallmark of chaos is what's known as ``se
 nsitivity to initial conditions" - two points that start arbitrarily close
  to each other will eventually have orbits that diverge from each other.  
 The deterministic logistic map has been well studied.  We are interested i
 n the \\emph{stochastic} logistic map - the map given when the $\\lambda$ 
 values take independent random values according to a distribution on $[0\,
 4]$.   Since there is a stochastic element to this map\, we can no longer 
 study the sequence of points given by taking iterates of the logistic maps
 \; the value of $f(x)$ is now a random variable\, and we study its distrib
 ution under successive iterates.  In this talk\, we'll explore what the pa
 ttern of distributions can tell us about the map\, and look for \\emph{inv
 ariant} distributions - distributions that remain fixed under successive i
 terates of the stochastic logistic map.\n

 >Extending differential forms across singularities</a>\nby Ben Tighe (Univ
 ersity of Illinois at Chicago) as part of Graduate Online Seminar Series (
 GOSS)\n\nLecture held in TBA.\n\nAbstract\nGiven a smooth projective varie
 ty $X$\, there are many contexts for which one can study "differentials" o
 n $X$.  When the ground field is $\\mathbf C$\, we may define "holomorphic
  differentials" on $X$ which often encapsulate the geometry of $X$ and sho
 w that these agree with the algebraic differentials that one encounters in
  a first-year algebraic geometry course in a very precise way.  \n\nWhen $
 X$ has singularities\, it no longer makes sense to define holomorphic diff
 erentials.  Moreover\, even though algebraic differentials exist for all v
 arieties\, they do not capture the geometry of $X$ in the same way holomor
 phic differentials do in the smooth case.  The aim of this talk will be to
  describe a suitable replacement in this setting.\n\nThe outline of the ta
 lk then will be as follows.  We will discuss how holomorphic differentials
  show up in complex algebraic geometry (Serre duality\, Kodaira vanishing\
 , Hodge decomposition theorem\, Serre GAGA).  We will then look at differe
 nt kinds of differentials on singular spaces and see how good they are at 
 replacing holomorphic differentials.  In particular\, we will look closely
  at reflexive differentials\, which inherit many properties that we see in
  the smooth case.  The last part of the talk will concern the "extension p
 roblem" for reflexive differentials.  Time permitting\, we will look at ap
 plications of the extension problem to recent work.\n

 >A RSK-Y Proposition</a>\nby Dan Summers (Chaminade High School) as part o
 f Graduate Online Seminar Series (GOSS)\n\nLecture held in TBA.\n\nAbstrac
 t\nIn this talk\, we will discuss two areas of mathematics\, Algebra and C
 ombinatorics\, which have been paired together with great results.  We pre
 sent two sets of combinatorial objects which are equinumerous\, the Robins
 on–Schensted–Knuth correspondence between these two sets\, and how the
  RSK correspondence can produce an unexpected result about the product of 
 two polynomials.  Along the way\, we examine some of the algebraic and com
 binatorial properties of the symmetric polynomials.\n
