# On Parabolic Subgroups of Symplectic Reflection Groups

2 Dec 2021

Using computational results required in the proof, we show the non-existence of symplectic resolutions for symplectic quotient singularities corresponding to three exceptional symplectic reflection groups, thus reducing further the number of cases for which the existence question remains open.

# Adaptation to DNA damage, an asymptotic approach for a cooperative non-local system

2 Dec 2021

Following previous works about integro-differential equations of parabolic type modelling the Darwinian evolution of a population, we study a two-population system in the cooperative case.

# Algorithm for monochromatic vertex-disconnection of graphs

1 Dec 2021

In addition, when mvd(G) is large and all blocks of G are minimally 2-connected triangle-free graphs, we characterize G. On these bases, we show that any graph whose blocks are all minimally 2-connected graphs of small order, can be computed mvd(G) and given an mvd-coloring in polynomial time.

# Asymptotically Optimal Sampling Policy for Selecting Top-m Alternatives

30 Nov 2021

To show the asymptotic optimality of the proposed procedure, the asymptotically optimal sampling ratios which optimize large deviations rate of the probability of false selection for selecting top-$m$ alternatives has been rigorously defined.

# The combinatorial method to compute the sum of the powers of primes

We will generalize the combinatorial algorithms for computing $\pi(x)$ to compute sums ${F(x) = \sum_{p \leq x} p^k}$ for $k \in \mathbb{Z}_{\geq 0}$.

# Incremental Proximal Multi-Forecast Model Predictive Control

29 Nov 2021

Multi-forecast model predictive control (MF-MPC) is a control policy that creates a plan of actions over a horizon for each of a given set of forecasted scenarios or contingencies, with the constraint that the first action in all plans be the same.

# A Random Active Set Method for Strictly Convex Quadratic Problem with Simple Bounds

27 Nov 2021

To guarantee the finite step convergence, the existing active set methods all need strict conditions or some additional strategies, which greatly affect the efficiency of the algorithm.

# First Betti number of the path homology of random directed graphs

26 Nov 2021

Path homology is a topological invariant for directed graphs, which is sensitive to their asymmetry and can discern between digraphs which are indistinguishable to the directed flag complex.
