ALGEBRAIC STRUCTURES ON THE TOPOLOGY OF MODULI SPACES OF CURVES AND MAPS
MODULI SPACES CURVES AND MAPS
2015/7/14
We discuss selected topics on the topology of moduli spaces
of curves and maps, emphasizing their relationwith GromovWitten theory and integrable systems
Interpolation problems by completely positive maps
Completely positive map quantum operations dilations Hermitian matrices
2011/1/19
Given commuting families of Hermitian matrices {A1, . . . ,Ak} and {B1, . . . ,Bk},conditions for the existence of a completely positive map Φ, such that Φ(Aj) = Bj for j =1, . . . , k, are studied. A...
A general comparison theorem for $p$-harmonic maps in homotopy class
comparison theorem homotopy class
2010/11/22
We prove a general comparison result for homotopic finite $p$-energy $C^{1}$ $p$-harmonic maps $u,v:M\to N$ between Riemannian manifolds, assuming that $M$ is $p$-parabolic and $N$ is complete and non...
Restriction maps on 1-cohomology of (algebraic) groups
Restriction maps on 1-cohomology of groups
2010/11/11
Our first theorem is a version of the five lemma in a certain situation of pointed sets arising from non-abelian 1-cohomology. For our second, we show that a connected, unipotent algebraic group Q ac...
Regular hyperbolicity, dominant energy condition and causality for Lagrangian theory of maps
Regular hyperbolicity dominant energy condition Lagrangian theory
2010/11/19
The goal of the present paper is three-fold. First is to clarify the connection between the dominant energy condition and hyperbolicity properties of Lagrangian field theories. Second is to provide fu...
Surfaces with $p_g = 0$, $K^2 = 5$ and bicanonical maps of degree 4
Surfaces bicanonical maps
2010/11/11
Let $S$ be a minimal surface of general type with $p_g(S) = 0, K_S^2 = 5$ and bicanonical map of degree 4. Denote by $\Sigma$ the bicanonical image. If $\Sigma$ is smooth, then $S$ is a Burniat surfa...
Normality of bounded and unbounded adjointable operators are discussed. Suppose $T$ is an adjointable operator between Hilbert C*-modules which has polar decomposition, then $T$ is normal if and only...
Renormalization group structure for sums of variables generated by incipiently chaotic maps
Renormalization group chaotic maps
2010/4/7
We look at the limit distributions of sums of deterministic chaotic variables in unimodal maps and find a remarkable renormalization group (RG) structure associated to the operation of increment of su...
Yang-Baxter Maps from the Discrete BKP Equation
Yang-Baxter Maps Discrete BKP Equation piecewise-linear
2010/4/7
We construct rational and piecewise-linear Yang-Baxter maps for a general N-reduction of the discrete BKP equation.
