SUMMARY:Classification of noncommutative subvarieties
DESCRIPTION:Lecturer:Jeet Sampat (Technion)\n Location:Faculty lounge\, 8th
floor\n Abstract:\n\nA corollary of Hilbert's Nullstellensatz is that the
quotient algebras of two\nradical ideals in the ring of (commutative) pol
ynomials in d complex variables\nare isomorphic to each other if and only
if the corresponding varieties are\nisomorphic\, in the sense that there e
xist polynomial maps between the ddimensional\ncomplex space that restrict
to mutually inverse bijections between\nthe corresponding varieties. In t
his talk\, we consider the noncommutative (nc)\nanalogue of the above resu
lt and answer the following questions:\nWhen are two nc varieties "isomorp
hic" to each other? What happens if we\nreplace the ring of complex polyno
mials with some other algebra of complex\nnc functions?\nWe start with a s
oft introduction to nc function theory and discuss some of the\nproperties
that general nc functions share. For the main result\, we use a\nremarkab
le theorem of Ball\, Marx\, and Vinnikov about extending nc functions\noff
of subvarieties to show that if the ambient space is "nice enough" then t
wo\nsubvarieties are isomorphic (in the sense that there is a bijective nc
map\nbetween the subvarieties) if and only if this isomorphism is given b
y the\nrestriction of an isomorphism between the ambient spaces.\n

SUMMARY:The fractal properties of the graphs of Weierstrass functions
DESCRIPTION:Lecturer:Haojie Ren (Technion)\n Location:Faculty Lounge 8th fl
oor Amado\n In this presentation\, we'll start by discussing Weierstrass f
unctions\, which are the most famous example of continuous nowhere differe
ntiable functions\, initially introduced by Weierstrass. Following that\,
we'll introduce the concept of fractal dimension and illustrate its calcul
ation using the Cantor set. Then\, we'll briefly review the historical con
text. Next\, we'll provide a simple proof of the box dimension of its grap
h\, and finally\, we'll introduce my result joint with Professor Weixiao S
hen.\n

SUMMARY:Mean curvature Flow and Applications
DESCRIPTION:Lecturer:Daniel Goldberg (Technion)\n Location:Faculty Lounge 8
th floor Amado\n A Hypersurface moving so as to decrease its area in the m
ost efficient way possible (in the L^2 norm) is said to evolve by Mean Cur
vature Flow. The Mean Curvature Flow is considered by many to be the most
natural equation in extrinsic geometry as it is the L^2 gradient flow of t
he area functional. In this talk we will introduce the Mean Curvature flow
by first deriving it as a gradient flow. Subsequently\, we will present i
ts basic properties including short time well-posedness\, maximum principl
e\, and some geometric attributes. Finally\, we will show applications of
the Mean Curvature Flow to material science and image processing. j\n
