On the growth of topological complexity
Daisuke Kishimoto, Atsushi Yamaguchi
Let denote the -th topological complexity of a space . In many cases, the generating function is a rational function…
The Steenrod algebra from the group theoretical viewpoint
Atsushi Yamaguchi
In the paper "The Steenrod algebra and its dual", J.Milnor determined the structure of the dual Steenrod algebra which is a graded commutative Hopf algebra of finite type. We consi…
On excess filtration on the Steenrod algebra
Atsushi Yamaguchi
In this note, we study some properties of the filtration of the Steenrod algebra defined from the excess of admissible monomials. We give several conditions on a cocommutative grad…
An Exact Bosonization Rule for c=1 Noncritical String Theory
N. Ishibashi, A. Yamaguchi
We construct a string field theory for c=1 noncritical strings using the loop variables as the string field. We show how one can express the nonrelativistic free fermions which des…
Universality of Nonperturbative Effects in c<1 Noncritical String Theory
Nobuyuki Ishibashi, Tsunehide Kuroki, Atsushi Yamaguchi
Nonperturbative effects in c<1 noncritical string theory are studied using the two-matrix model. Such effects are known to have the form fixed by the string equations but the numer…
On the Chemical Potential of D-instantons in c=0 Noncritical String Theory
Nobuyuki Ishibashi, Atsushi Yamaguchi
We study the chemical potential of D-instantons in c=0 noncritical string theory. In a recent work(hep-th/0405076), it was shown that the chemical potential can be calculated using…
