Quillen equivalences for truncated multicomplexes
Jiahao Hu
We establish Quillen equivalences between successive truncations of multicomplexes for the model structures that detect weak equivalences simultaneously on prescribed pages of the…
Bott-Chern and Aeppli homotopy
Jiahao Hu
This paper introduces Bott-Chern and Aeppli homotopy sets for a fibrant class of bisimplicial sets and establishes their basic properties. In positive bidegrees, Bott-Chern homotop…
Obstruction Theory for Bigraded Differential Algebras
Jiahao Hu
We develop an obstruction theory for Hirsch extensions of cbba's with twisted coefficients. This leads to a variety of applications, including a structural theorem for minimal cbba…
Invariants of real vector bundles
Jiahao Hu
For a compact smooth manifold with corners (or finite CW-complex) , we can prescribe a finite set of spin or spin manifolds (possibly with boundary) mapping into it so that…
Characterization of differential K-theory by hexagon diagram
Jiahao Hu
Using a canonical topology on differential K-theory induced from the Frechét space topology on differential forms and the discrete topology on topological K-theory, we prove that d…
On the algebra generated by
Shamuel Auyeung, Jin-Cheng Guu, Jiahao Hu
In this note, we determine the structure of the associative algebra generated by the differential operators that act on complex-value…
Investigation of the characteristics of the dual-band electromagnetic induction transparent-like terahertz spectrum in a grating-like structure
Chaoying Zhao, Jiahao Hu
In this paper, a new structure is proposed which is expected to realize dual-band electromagnetically induced transparency (EIT)-like effect in terahertz spectrum. It can be regard…
Almost complex manifolds with total Betti number three
Jiahao Hu
We show the minimal total Betti number of a closed almost complex manifold of dimension is four, thus confirming a conjecture of Sullivan except for dimension . Along…
Infinite symmetric products of rational algebras and spaces
Jiahao Hu, Aleksandar Milivojević
We show that the infinite symmetric product of a connected graded-commutative algebra over the rationals is naturally isomorphic to the free graded-commutative algebra on the posit…
